[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] Windows XP

You can double click on the two computers on the task bar at the lower right hand corner also known as your Local Area Connection. Once that opens you can see the status of your local area connection as well as the activity of it. The status referring to whether or not it's connected, how long it has been connected, and the speed of the connection. The activity referring to the number of packets sent and received. Then you click the Support tab. The support tab shows you your IP address, the address type, subnet mask and default gateway if you have one. You can also click details. Details shows you your Physical (MAC) address, IP address, the subnet mask address, the address for your DHCP server, your DNS server as well as when you obtained the lease for your IP address and when it expires.

[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
