Nslookup - Asus RX3042H User Manual

RX3042H User's Manual
Troubleshooting
Using the ping command, you can test whether the path to the
RX3042H is working (using the preconfigured default LAN IP
address 192.168.1.1) or another address you assigned.
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.

12.1.2 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 ISPʼs 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
you are interested in, such as www.absnews.com.
The window will display the associate IP address, if known, as
shown in Figure 12.2.
