[edit] Finding Your Local IP Address (broadband) or Global IP Address (dialup)

[edit] Windows 98 And Above

  1. Go to Start
  2. Click on Run
  3. Type cmd and hit enter (use command in Win98)
  4. Type ipconfig and hit enter

It will say something like

 Windows IP Configuration
 Ethernet adapter Local Area Connection Network Connection:
 Connection-specific DNS Suffix . :
 IP Address. . . . . . . . . . . . : 192.168.0.102 <-your IP address
 Subnet Mask . . . . . . . . . . . : 255.255.255.0
 Default Gateway . . . . . . . . . : 192.168.0.1     <-your system Gateway

If you are on broadband, or use a network modem or your internet connection is not through your current PC, that IP is a local ip. Meaning, that is the IP my router gave me, not the IP the world sees. This means that the address is only specific to me in my local network.

If you use dialup with a modem on your current computer, that will be your external IP.

[edit] Linux

  1. Open a Terminal/Console
  2. Type ifconfig
  3. Look at inet addr: xx.xx.xx.xx where the xx is your IP
[root@wikibooks]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:80:C8:F8:4A:51
          inet addr:192.168.99.35  Bcast:192.168.99.255  Mask:255.255.255.0

[edit] Finding Your Global IP Address

To find your global IP which is what the outside world sees, you may use a website such as WhatIsMyIP or IP Chicken.
