on the workstation’s Command Line. If the server is connected I will
receive a response to my ping. Note: It's easy to fi nd a computer's
ip address. Go to the target computer (the one you wish to ping)
and on its command line enter "ipconfi g". The ip address (and other
addresses will be displayed). More information on the ipconfi g com-
mand can be found later in this section
The Ping program has endless uses. Ping an address (as
above): If you get a response using the IP address but do not get
a response using the DNS address, there must be a problem with
the DNS system. If you suspect this, try another debugging program
"nslookup". On the command line enter nslookup followed by
the DNS name (enter nslookup www. bytebrothers.com) and see if
the IP address is displayed. If it is, your DNS appears to be working
correctly. Ping yourself: You can use the ping command to ping
yourself, either using your own IP address or what is known as
the loopback address. The loopback address is a special reserved
address that works on all systems:127.0.0.1 (enter ping 127.0.0.1).
If you would like to try pinging your own workstation address but do
not know it use the "ipconfi g" command (see below). Pinging
yourself is the fi rst test that should be conducted because if it fails
it most likely means that TCP/IP is not properly loaded on the
workstation. If it passes and you were using your own IP address
(not the loopback address), it confi rms that you are the only one
on the network with that address. Ping your gateway: If you get
a response it means that the packets are making it to the router (a
gateway is a device on a network that serves as an entrance to
another network). On business LANs the gateway is generally the
router. In homes, the gateway is the ISP (internet service provider)
that connects the user to the internet.
