TCP/IP:

Plz in order to understand completely, do not skip any part and read in the same manner. 

IP Address - 32 bit address used to uniquely identify a TCP/IP host.   The address has two parts.  The network ID and the host ID.  The network ID identifies all hosts that are on the same logical network.  The host ID identifies the host.  Hosts can be workstations, Servers, Routers, ex..  A sample IP address is 209.124.223.67
Lets compare this to the Calendar.  We have 12 Networks:   January, February, March.... On each Network, we have hosts: 1,2,3,4...
January 1 and January 14 are unique hosts on the same network.   March 4 and June 17 are on different networks. 

  Example:

   209.124.223.67

   |   |   |   |

   |   |   |   |-->(4th octet,8-bits,Ranges from 0 to 255)

   |   |   |-------->(3rd octet,8-bits,Ranges from 0 to 255)

   |   |------------>(2nd octet,8-bits,Ranges from 0 to 255)              

   |---------------->(1st octet,8-bits,Ranges from 0 to 255)

Total bits = 8bit+8bit+8bit+8bit=32bits.
 

 Tools for finding IP address :

Basically you do not need any tools, command prompt is sufficient. But still if you don't want to use command prompt there are tools.

  • X-Netstat - It's a program that gets the ips ports and host names of any ip thats connected to your ip.
  • Whois  - This is a program that tells you the ips isp and tells the address of the isp.

 By using Command Prompt : Another way is by using the  command NETSTAT -N in the command prompt. Type the command in the netstat and it will show you the all the ip's connected to your ip.

If you don't know how to get to command prompt see the previous page.

 

Netstat -n :  Type netstat - n in the command prompt. Make sure you are connected.

  Your Command Prompts Screen Should Look Similar To This: 

 Active Connections

  Proto   Local Address       Foreign Address              State

  TCP     12.215.186.232       207.46.4.83:1863                ESTABLISHED

  TCP     12.215.186.232       209.249.116.141:80            CLOSE_WAIT

  TCP     12.215.186.232       64.86.101.45:80                  CLOSE_WAIT

  TCP     12.215.186.232       216.155.193.151:5050        ESTABLISHED 

Active Connections = Showing You That Below Is Your Active Connections 

Proto = The Protocol Your Are Connected Thru

Local Address = Your Local Internet Protocol Address

Foreign Address = The Remote Internet Protocol Address Your Connected To And The Remote Port Connected Thru Afterwards

State = The Connection State

 

EXAMPLE....  Proto    Local Address       Foreign Address               State

                        TCP     12.215.186.232        207.46.4.83:1863                ESTABLISHED

 

You Are Connected To 207.46.4.83 <Remote Ip>   On The Transmission Control Protocol Thru Remote Port 1863  From 12.215.186.232 <Your Local Ip> And The Connection Is An Established Connection Meaning You Are Constantly Connected To This Ip.

 

How do I find my own IP address? :

Windows 95/98/ME:

1. Click the Start button then press Run.

2. In the Run dialog box, type in WINIPCFG in the white space and press OK.

3. An IP Configuration box should pop up with the IP displayed.


Windows 2000

1. Click START, go to Programs, then go to Accessories, and select the Command Prompt.

2. The Command Prompt window will open. Type "ipconfig/all" and hit the RETURN key.


Windows NT

1. Click the Start button then press Run.

2. In the Run dialog box, type in IPCONFIG in the white space and press OK.

 

Remeber: Be sure to be connected while finding the ip address.
