address, such as that for
www.yahoo.com
(216.115.108.243). If you do not know the
IP address of a particular Internet location, you can use the
nslookup
command, as
explained in the following section.
For most other IP-enabled operating systems, you can execute the same command at
a command prompt or through a system administration utility.
Nslookup
You can use the
nslookup
command to determine the IP address associated with an
Internet site name. You specify the common name, and the
nslookup
command looks
up the name on your DNS server (usually located with your ISP). If that name is not an
entry in your ISP’s DNS table, the request is then referred to another higher-level
server, and so on, until the entry is found. The server then returns the associated IP
address.
On Windows-based computers, you can execute the
nslookup
command from the
Start menu. Click the
Start
button, and then click
Run
. In the
Open
text box, type the
following:
Nslookup
Click
OK
. A
Command Prompt
window displays with a bracket prompt (>). At the
prompt, type the name of the Internet address that you are interested in, such as
www.microsoft.com
.
The window will display the associate IP address, if known, as shown below:
There may be several addresses associated with an Internet name. This is common
for web sites that receive heavy traffic; they use multiple, redundant servers to carry
the same information.
To exit from the nslookup utility, type
exit
and press
[Enter]
at the command prompt.
