Get the IP Adress of REmote Computer 07.25

IP address is a unique 32-bit address assigned to each computer on the Internet,
and is the central component of the TCP/IP network protocol.
An IP address is usually written as a quartet of integer numbers (e.g. 192.64.16.8).
Also, a computer typically has a hostname that is easier to memorize and use than a numeric
address.
Knowing computer name allows to find out the IP address and vice versa.

1. 1
   Click "Start" then "Run" Type "cmd" and press "Enter" (in Windows XP).
   Click "Start" and type "cmd" in Start Search field. Press "Enter" (in Windows Vista).
   In both cases, the new window with a black background should appear.
2. 2
   In the window type ping <remote computer name> and press "Enter."
   Example:
   ping xrlab.ineos.ac.ru
3. 3
   
   Read the ping program output; the first line always contains IP address of the remote computer in brackets.
   Example: pinging xrlab.ineos.ac.ru [193.233.4.27] ...
4. 4
   Type "Exit" and press "Enter" to close the window.
   
   
   Tips & Warning:-Do not pay Attention to the rest of ping results. The actual pinging May be Blocked by a remote Machine  For security reason

IP Spoofing Attack 23.36

The term IP (Internet Protocol) address spoofing refers to the creation of IP packets with a forged (spoofed) source IP address with the purpose of concealing the identity of the sender or impersonating another computing system.

Why it works ?
IP-Spoofing works because trusted services only rely on network address based authentication. Since IP is easily duped, address forgery is not difficult.
The main reason is security weakness in the TCP protocol known as sequence number prediction.

How it works ?

every computer connected to Network have its unique IP address.
When Person A sends an email  to person B, The mail is assigned with the header which contains the IP’s of sender and Reciver so that mail can go to the same person B and not to some one else.
Now in a private network for security reasons limited mails are accpeted from reserved IP’s.
In Simple word only internal communication can be worked. Person from outside can’t send mail in that network.
So if attacker wants send the mail inside, He will spoof the IP.
He first will sniffs the data packets in the internal communication adn steal some internal email.
Then he will perform changing in header of the mail. he will change content of the mail and send this mail to network again.
System cant provide security against this because it have internal fake IP.
This is how fake IP  is created and attack of spoofing is don




Internet Protocol (IP) :
It is a network protocol operating at layer 3 (network) of the OSI model. It is a connectionless model, meaning there is no information regarding transaction state, which is used to route packets on a network. Additionally, there is no method in place to ensure that a packet is properly delivered to the destination.

Examining the IP header, we can see that the first 12 bytes (or the top 3 rows of the header) contain various information about the packet. The next 8 bytes (the next 2 rows), however, contains the source and destination IP addresses. Using one of several tools, an attacker can easily modify these addresses – specifically the “source address” field.

Transmission Control Protocol (TCP) :
It is the connection-oriented, reliable transport protocol in the TCP/IP suite. Connection-oriented simply means that the two hosts participating in a discussion must first establish a connection via the 3-way handshake (SYN-SYN/ACK-ACK). Reliability is provided by data sequencing and acknowledgement. TCP assigns sequence numbers to every segment and acknowledges any and all data segments recieved from the other end.

As you can see above, the first 12 bytes of the TCP packet, which contain port and sequencing information.

TCP sequence numbers can simply be thought of as 32-bit counters. They range from 0 to 4,294,967,295. Every byte of data exchanged across a TCP connection (along with certain flags) is sequenced. The sequence number field in the TCP header will contain the sequence number of the *first* byte of data in the TCP segment. The acknowledgement number field in the TCP header holds the value of next *expected* sequence number, and also acknowledges *all* data up through this ACK number minus one.

TCP packets can be manipulated using several packet crafting softwares available on the internet.

The Attack
IP-spoofing consists of several steps. First, the target host is choosen. Next, a pattern of trust is discovered, along with a trusted host. The trusted host is then disabled, and the target's TCP sequence numbers are sampled. The trusted host is impersonated, the sequence numbers guessed, and a connection attempt is made to a service that only requires address-based authentication. If successful, the attacker executes a simple command to leave a backdoor.

Spoofing can be implemented by different ways as given below -

Non-Blind Spoofing :- This type of attack takes place when the attacker is on the same subnet as the victim. The sequence and acknowledgement numbers can be sniffed, eliminating the potential difficulty of calculating them accurately.

Blind Spoofing :- Here the sequence and acknowledgement numbers are unreachable. In order to circumvent this, several packets are sent to the target machine in order to sample sequence numbers.

Both types of spoofing are forms of a common security violation known as a Man In The Middle Attack. In these attacks, a malicious party intercepts a legitimate communication between two friendly parties. The malicious host then controls the flow of communication and can eliminate or alter the information sent by one of the original participants without the knowledge of either the original sender or the recipient. In this way, an attacker can fool a victim into disclosing confidential information by “spoofing” the identity of the original sender, who is presumably trusted by the recipient.

IP spoofing is almost always used in what is currently one of the most difficult attacks to defend against – Denial of Service attacks, or DoS.

How to Hack Someone by Knowing His IP 23.15

Introduction
1. Welcome to the basic NETBIOS post created by sumit. This document will teach you some simple things about NETBIOS, what it does, how to use it, how to hack with it, and some other simple DOS commands that will be useful to you in the future. THIS DOCUMENT IS FOR NEWBIEZ ONLY!!! If you are newbie then must read this full article,it helps you to understand netbios hack,thr is more simple trick to hack someone by netbios but this article give u full knowledge about netbios hacking

1. Hardware and Firmware

1a. The BIOS
The BIOS, short for Basic Input/Output Services, is the control program of the PC. It is responsible for starting up your computer, transferring control of the system to your operating system, and for handling other low-level functions, such as disk access.
NOTE that the BIOS is not a software program, insofar as it is not purged from memory when you turn off the computer. It's 
firmware, which is basically software on a chip.
A convenient little feature that most BIOS manufacturers include is a startup password. This prevents access to the system until you enter the correct password.
If you can get access to the system after the password has been entered, then there are numerous software-based BIOS password extractors available from your local H/P/A/V site.
NETBIOS/NBTSTAT - What does it do?

2. NETBIOS, also known as NBTSTAT is a program run on the Windows system and is used for identifying a remote network or computer for file sharing enabled. We can expoit systems using this method. It may be old but on home pc's sometimes it still works great. You can use it on your friend at home or something. I don't care what you do, but remember, that you are reading this document because you want to learn. So I am going to teach you. Ok. So, you ask, "How do i get to NBTSTAT?" Well, there are two ways, but one's faster.
Method 1:Start>Programs>MSDOS PROMPT>Type NBTSTAT 
Method 2:Start>Run>Type Command>Type NBTSTAT
(Note: Please, help your poor soul if that isn't like feeding you with a baby spoon.)
Ok! Now since you're in the DOS command under NBTSTAT, you're probably wondering what all that crap is that's on your screen. These are the commands you may use. I'm only going to give you what you need to know since you are striving to be l33t. Your screen should look like the following:

NBTSTAT [ [-a RemoteName] [-A IP address] [-c] [-n]
[-r] [-R] [-RR] [-s] [-S] [interval] ]
-a (adapter status) Lists the remote machine's name table given its name
-A (Adapter status) Lists the remote machine's name table given its IP address.
-c (cache) Lists NBT's cache of remote [machine] names and their IP addresses
-n (names) Lists local NetBIOS names.
-r (resolved) Lists names resolved by broadcast and via WINS
-R (Reload) Purges and reloads the remote cache name table
-S (Sessions) Lists sessions table with the destination IP addresses
-s (sessions) Lists sessions table converting destination IP addresses to computer NETBIOS names.
-RR (ReleaseRefresh) Sends Name Release packets to WINS and then, starts Refresh
RemoteName Remote host machine name.
IP address Dotted decimal representation of the IP address.
interval Redisplays selected statistics, pausing interval seconds between each display. Press Ctrl+C to stop redisplaying
statistics.
C:\WINDOWS\DESKTOP>
The only two commands that are going to be used and here they are:
-a (adapter status) Lists the remote machine's name table given its name
-A (Adapter status) Lists the remote machine's name table given its IP address.
Host Names

3. Now, the -a means that you will type in the HOST NAME of the person's computer that you are trying to access. Just in case you don't have any idea what a Host Name looks like here's an example.
123-fgh-ppp.internet.com
there are many variations of these adresses. For each different address you see there is a new ISP assigned to that computer. look at the difference.
abc-123.internet.com
ghj-789.newnet.com
these are differnet host names as you can see, and, by identifying the last couple words you will be able to tell that these are two computers on two different ISPs. Now, here are two host names on the same ISP but a different located server.
123-fgh-ppp.internet.com
567-cde-ppp.internet.com
IP Addresses
4. You can resolce these host names if you want to the IP address (Internet Protocol)
IP addresses range in different numbers. An IP looks like this:
201.123.101.123
Most times you can tell if a computer is running on a cable connection because of the IP address's numbers. On faster connections, usually the first two numbers are low. here's a cable connection IP.
24.18.18.10
on dialup connections IP's are higher, like this:
208.148.255.255
notice the 208 is higher than the 24 which is the cable connection.
REMEMBER THOUGH, NOT ALL IP ADDRESSES WILL BE LIKE THIS.
Some companies make IP addresses like this to fool the hacker into believing it's a dialup, as a hacker would expect something big, like a T3 or an OC-18. Anyway This gives you an idea on IP addresses which you will be using on the nbtstat command.
Getting The IP Through DC (Direct Connection)
5. First. You're going to need to find his IP or host name. Either will work. If you are on mIRC You can get it by typing /whois (nick) ...where (nick) is the persons nickname without parenthesis. you will either get a host name or an IP. copy it down. If you do not get it or you are not using mIRC then you must direct connect to their computer or you may use a sniffer to figure out his IP or host name. It's actually better to do it without the sniffer because most sniffers do not work now-a-days. So you want to establish a direct connection to their computer. OK, what is a direct connection? When you are:
Sending a file to their computer you are directly connected.
AOL INSTANT MESSENGER allows a Direct Connection to the user if accepted.
ICQ when sending a file or a chat request acception allows a direct connection.
Any time you are sending a file. You are directly connected. (Assuming you know the user is not using a proxy server.)
Voice Chatting on Yahoo establishes a direct connection.
If you have none of these programs, either i suggest you get one, get a sniffer, or read this next statement.
If you have any way of sending thema link to your site that enables site traffic statistics, and you can log in, send a link to your site, then check the stats and get the IP of the last visitor. It's a simple and easy method i use. It even fool some smarter hackers, because it catches them off guard. Anyway, once you are directly 
connected use either of the two methods i showed you earlier and get into DOS. Type NETSTAT -n. NETSTAT is a program that's name is short for NET STATISTICS. It will show you all computers connected to yours. (This is also helpful if you think you are being hacked by a trojan horse and is on a port that you know such as Sub Seven: 27374.) Your screen should look like this showing the connections to your computer:
---------------------------------------------------------------------------------------
C:\WINDOWS\DESKTOP>netstat -n
Active Connections
Proto Local Address Foreign Address State
TCP 172.255.255.82:1027 205.188.68.46:13784 ESTABLISHED
TCP 172.255.255.82:1036 205.188.44.3:5190 ESTABLISHED
TCP 172.255.255.82:1621 24.131.30.75:66 CLOSE_WAIT
TCP 172.255.255.82:1413 205.188.8.7:26778 ESTABLISHED
TCP 172.255.255.82:1483 64.4.13.209:1863 ESTABLISHED
C:\WINDOWS\DESKTOP>
--------------------------------------------------------------------------------------

The first line indicated the Protocol (language) that is being used by the two computers.
TCP (Transfer Control Protocol) is being used in this and is most widely used.
Local address shows your IP address, or the IP address of the system you on.
Foreign address shows the address of the computer connected to yours.
State tells you what kind of connection is being made ESTABLISHED - means it will stay connected to you as long as you are on the program or as long as the computer is allowing or is needing the other computers connection to it. CLOSE_WAIT means the connection closes at times and waits until it is needed or you resume connection to be made again. One that isn't on the list is TIME_WAIT which means it is timed. Most Ads that run on AOL are using TIME_WAIT states.
the way you know the person is directly connected to your computer is because of this:
-----------------------------------------------------------------------------------
C:\WINDOWS\DESKTOP>netstat -n
Active Connections
Proto Local Address Foreign Address State
TCP 172.255.255.82:1027 205.188.68.46:13784 ESTABLISHED
TCP 172.255.255.82:1036 205.188.44.3:5190 ESTABLISHED
TCP 172.255.255.82:1621 24.131.30.75:66 CLOSE_WAIT
TCP 172.255.255.82:1413 abc-123-ppp.webnet.com ESTABLISHED
TCP 172.255.255.82:1483 64.4.13.209:1863 ESTABLISHED
C:\WINDOWS\DESKTOP>
----------------------------------------------------------------------------------
Notice the host name is included in the fourth line instead of the IP address on all. This is almost ALWAYS, the other computer that is connected to you. So here, now, you have the host name:
abc-123-ppp.webnet.com
If the host name is not listed and the IP is then it NO PROBLEM because either one works exactly the same. I am using abc-123-ppp.webnet.com host name as an example. Ok so now you have the IP and/or host name of the remote system you want to connect to. Time to hack!
Open up your DOS command. Open up NBTSTAT by typing NBTSTAT. Ok, there's the crap again. Well, now time to try out what you have leanred from this document by testing it on the IP and/or host name of the remote system. Here's the only thing you'll need to know.
IMPORTANT, READ NOW!!!
-a (adapter status) Lists the remote machine's name table given its name
-A (Adapter status) Lists the remote machine's name table given its IP address.
Remember this?
Time to use it.
-a will be the host name 
-A will be the IP
How do i know this?
Read the Statements following the -a -A commands. It tells you there what each command takes.
So have you found which one you have to use?
GOOD!
Time to start.
Using it to your advantage
6. Type this if you have the host name only.
NBTSTAT -a (In here put in hostname without parenthesis)
Type this is you have the IP address only.
NBTSTAT -A (In here put in IP address without parenthesis)
Now, hit enter and wait. Now Either one of two things came up
1. Host not found
2. Something that looks like this:
--------------------------------------------
NetBIOS Local Name Table
Name Type Status
---------------------------------------------
GMVPS01 <00> UNIQUE Registered
WORKGROUP <00> GROUP Registered
GMVPS01 <03> UNIQUE Registered
GMVPS01 <20> UNIQUE Registered
WORKGROUP <1E> GROUP Registered
---------------------------------------------
If the computer responded "Host not found" Then either one of two things are the case:
1. You screwed up the host name.
2. The host is not hackable.
If number one is the case you're in great luck. If two, This system isn't hackable using the NBTSTAT command. So try another system.
If you got the table as above to come up, look at it carefully as i describe to you each part and its purpose.
Name - states the share name of that certain part of the computer
<00>, <03>, <20>, <1E> - Are the Hexidecimal codes giving you the services available on that share name.
Type - Is self-explanatory. It's either turned on, or activated by you, or always on.
Status - Simply states that the share name is working and is activated.
Look above and look for the following line:
GMVPS01 <20> UNIQUE Registered
See it?
GOOD! Now this is important so listen up. The Hexidecimanl code of <20> means that file sharing is enabled on the share name that is on that line with the hex number. So that means GMVPS01 has file sharing enabled. So now you want to hack this. Here's How to do it. (This is the hard part)
LMHOST File
7. There is a file in all Windows systems called LMHOST.sam. We need to simply add the IP into the LMHOST file because LMHOST basically acts as a network, automatically logging you on to it. So go to Start, Find, FIles or Folders. Type in LMHOST and hit enter. when it comes up open it using a text program such as wordpad, but make sure you do not leave the checkmark to "always open files with this extension" on that. Simply go through the LMHOST file until you see the part:
# This file is compatible with Microsoft LAN Manager 2.x TCP/IP lmhosts
# files and offers the following extensions:
#
# #PRE
# #DOM:
# #INCLUDE 
# #BEGIN_ALTERNATE
# #END_ALTERNATE
# \0xnn (non-printing character support)
#
# Following any entry in the file with the characters "#PRE" will cause
# the entry to be preloaded into the name cache. By default, entries are
# not preloaded, but are parsed only after dynamic name resolution fails.
#
# Following an entry with the "#DOM:" tag will associate the
# entry with the domain specified by . This affects how the
# browser and logon services behave in TCP/IP environments. To preload
# the host name associated with #DOM entry, it is necessary to also add a
# #PRE to the line. The is always preloaded although it will not
# be shown when the name cache is viewed.
#
# Specifying "#INCLUDE " will force the RFC NetBIOS (NBT)
# software to seek the specified and parse it as if it were
# local. is generally a UNC-based name, allowing a

# centralized lmhosts file to be maintained on a server.
# It is ALWAYS necessary to provide a mapping for the IP address of the
# server prior to the #INCLUDE. This mapping must use the #PRE directive.
# In addtion the share "public" in the example below must be in the
# LanManServer list of "NullSessionShares" in order for client machines to
# be able to read the lmhosts file successfully. This key is under
# \machine\system\currentcontrolset\services\lanmans erver\parameters\nullsessionshares
# in the registry. Simply add "public" to the list found there.
#
# The #BEGIN_ and #END_ALTERNATE keywords allow multiple #INCLUDE
# statements to be grouped together. Any single successful include
# will cause the group to succeed.
#
# Finally, non-printing characters can be embedded in mappings by
# first surrounding the NetBIOS name in quotations, then using the
# \0xnn notation to specify a hex value for a non-printing character.
Read this over and over until you understand the way you want your connection to be set. Here's an example of how to add an IP the way I would do it:
#PRE #DOM:255.102.255.102 #INCLUDE 
Pre will preload the connection as soon as you log on to the net. DOM is the domain or IP address of the host you are connecting to. INCLUDE will automaticall set you to that file path. In this case as soon as I log on to the net I will get access to 255.102.255.102 on the C:/ drive. The only problem with this is that by doin the NETSTAT command while you are connected, and get the IP of your machine. That's why it only works on simple PC machines. Because people in these days are computer illiterate and have no idea of what these commands can do. They have no idea what NETSTAT is, so you can use that to your advantage. Most PC systems are kind of hard to hack using this method now because they are more secure and can tell when another system is trying to gain access. Also, besure that you (somehow) know whether they are running a firewall or not because it will block the connection to their computer. Most home systems aren't running a firewall, and to make it better, they don't know how operate the firewall, therefore, leaving the hole in the system. To help you out some, it would be a great idea to pick up on some programming languages to show you how the computer reads information and learn some things on TCP/IP (Transfer Control Protocol/Internet Protocol) If you want to find out whether they are running a firewall, simply hop on a Proxy and do a port scan on their IP. You will notice if they are running a firewall because most ports are closed. Either way, you still have a better chance of hacking a home system than hacking Microsoft.
Gaining Access
7. Once you have added this to you LMHOST file. You are basically done. All you need to do is go to:
Start
Find
Computer
Once you get there you simply type the IP address or the host name of the system. When it comes up, simply double click it, and boom! There's a GUI for you so you don't have to use DOS anymore. You can use DOS to do it, but it's more simple and fun this way, so that's the only way i put it. When you open the system you can edit, delete, rename, do anything to any file you wish. I would also delete the command file in C:/ because they may use it if they think someone is in their computer. Or simply delete the shortcut to it. Then here's when the programming comes in handy. Instead of using the NBTSTAT method all the time, you can then program you own trojan on your OWN port number and upload it to the system. Then you will have easier access and you will also have a better GUI, with more features. DO NOT allow more than one connection to the system unless they are on a faster connection. If you are downloading something from their computer and they don't know it and their connection is being slow, they may check their NETSTAT to see what is connected, which will show your IP and make them suspicious. Thats it. All there is to it. Now go out and scan a network or something and find a computer with port 21 or something open.

What is IP and How to get the IP of a Remote System 23.04

Getting the IP or Internet Protocol of a remote system is the most important and the first step of hacking into it. Probably it is the first thing a hacker do to get info for researching on a system. Well IP is a unique number assigned to each computer on a network. It is this unique address which represents the system on the network. Generally the IP of a particular system changes each time you log on to the network by dialing to your ISP and it is assigned to you by your ISP. IP of a system which is always on the network remains generally the same. Generally those kind of systems are most likely to suffer a hacking attack because of its stable IP. Using IP you can even execute system commands on the victim’s computer.
Lets take the example of the following IP address: 202.144.49.110 Now the first part, the numbers before the first decimal i.e. 209 is the Network number or the Network Prefix.. This means that it identifies the number of the network in which the host is. The second part i.e. 144 is the Host Number that is it identifies the number of the host within the Network. This means that in the same Network, the network number is same. In order to provide flexibility in the size of the Network, here are different classes of IP addresses:

Address Class Dotted Decimal Notation Ranges
Class A ( /8 Prefixes) 1.xxx.xxx.xxx through 126.xxx.xxx.xxx
Class B ( /16 Prefixes) 128.0.xxx.xxx through 191.255.xxx.xxx
Class C ( /24 Prefixes) 192.0.0.xxx through 223.255.255.xxx

The various classes will be clearer after reading the next few lines.

Each Class A Network Address contains a 8 bit Network Prefix followed by a 24-bit host number. They are considered to be primitive. They are referred to as "/8''s" or just "8's" as they have an 8-bit Network prefix.
In a Class B Network Address there is a 16 bit Network Prefix followed by a 16-bit Host number. It is referred to as "16's".

A class C Network address contains a 24-bit Network Prefix and a 8 bit Host number. It is referred to as
"24's" and is commonly used by most ISP's.

Due to the growing size of the Internet the Network Administrators faced many problems. The Internet routing tables were beginning to grow and now the administrators had to request another network number from the Internet before a new network could be installed at their site. This is where sub-netting came in.

Now if your ISP is a big one and if it provides you with dynamic IP addresses then you will most probably see that whenever you log on to the net, your IP address will have the same first 24 bits and only the last 8 bits will keep changing. This is due to the fact that when sub-netting comes in then the IP Addresses structure becomes:

xxx.xxx.zzz.yyy

where the first 2 parts are Network Prefix numbers and the zzz is the Subnet number and the yyy is the host number. So you are always connected to the same Subnet within the same Network. As a result the first 3 parts will remain the same and only the last part i.e. yyy is variable.
***********************

For Example, if say an ISP xyz is given the IP: 203.98.12.xx Network address then you can be awarded any IP, whose first three fields are 203.98.12. Get it?

So, basically this means that each ISP has a particular range in which to allocate all its subscribers. Or in other words, all subscribers or all people connected to the internet using the same ISP, will have to be in this range. This in effect would mean that all people using the same ISP are likely to have the same first three fields of their IP Addresses.

This means that if you have done a lot of (By this I really mean a lot) of research, then you could figure out which ISP a person is using by simply looking at his IP. The ISP name could then be used to figure out the city and the country of the person. Right? Let me take an example to stress as to how cumbersome but easy (once the research is done) the above method can be.

In my country, say there are three main ISP’s:

ISP Name Network Address Allotted

ISP I 203.94.47.xx
ISP II 202.92.12.xx
ISP III 203.91.35.xx

Now, if I get to know the IP of an e-pal of mine, and it reads: 203.91.35.12, then I can pretty easily figure out that he uses ISP III to connect to the internet. Right? You might say that any idiot would be able to do this. Well, yes and no. You see, the above method of finding out the ISP of a person was successful only because we already had the ISP and Network Address Allotted list with us. So, what my point is, that the above method can be successful only after a lot of research and experimentation. And, I do think such research can be helpful sometimes.

Also, this would not work, if you take it all on in larger scale. What if the IP that you have belongs to someone living in a remote igloo in the North Pole? You could not possibly get the Network Addresses of all the ISP’s in the world, could you? If yes please send it to me ?.

Well now I guess you have pretty good knowledge about what an IP is and what you can do by knowing the IP of a remote system. Now lets come to the point of finding out the IP of remote system.
Well you can easily figure out the IP of a remote system using the netstat utility available in the microsoft’s version of DOS. The netstat command shows the connections in which your system is engaged to and the ports they are using. Suppose you are checking your mail in hotmail and you want to find out the IP of msn. All you need to do is to open a dos window (command.com) and type netstat. You will see all the open connections of your system. There you will see something :

Proto Local Address Foreign Address State
TCP abhisek:1031 64.4.xx.xx:80 ESTABLISHED

Now you got the IP address of hotmail ass 64.4.xx.xx .
Similarly you can figure out the IP address of most http or ftp connections.

To know your own IP type the following command in a dos windows
C:\netstat –n
[this commands converts the IP name into IP addresses]
this is what you will probably see on typing the above command :

Proto Local Address Foreign Address State
TCP 203.xx.251.161:1031 194.1.129.227:21 ESTABLISHED

Here 203.xx.251.161 is your IP address.

Now lets clarify the format used by netstat :

Proto : It shows the type of protocol the connection with the remote system is using.
Here TCP (transmission control protocol) is the protocol used by my system to connect to other systems.

Local Address : It shows the local address ie the local IP. When the netstat command is executed without –n switch then the name of the local system is displayed and when the netstat is executed with –n switch then the IP of the local system is displayed. Here you can also find out the port used by the connection.
xxx.yyy.zzz.aaa:1024
in this format you will see the local address. Here 1024 is the port to which the remote system is connected in your system

Foreign Address :: It shows the IP address of the remote system to which your system is connected. In this case also if the netstat command is excuted with –n switch then you directly get the IP of the victim but if the netstat is executed without –n switch then you will get the address of the remote system. Something like

C:\netstat
Proto Local Address Foreign Address State
TCP abhisek:1031 msgr.lw4.gs681.hotmail.com:80 ESTABLISHED
