Nslookup - Inteno FG101 User Manual

FG101 User's Guide
You can also test whether access to the Internet is working by typing an external
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.
From 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 in 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.
