port on a switch. When you have a connection to

• Before your computer can communicate with other
  computers on a network, it must have an address.
  On your network, this address is known as an IP
  address.

In order to view your IP address on a Windows XP
or Windows 2000 computer, you can open a command
prompt window

At the command prompt, type ipconfig. Then,
hit enter. Basic IP address information will be
displayed. Here, you can see that my IP address
is 10.3.0.218.

connected to the network. After using the
ipconfig utility to see your IP address
information, note that you can also see an
address for Default Gateway. In this case, you
can see that my default gateway is 10.3.0.1. At
the prompt, type ping gateway address. If
you get a reply, youre connected.
