To check the connectivity with the Internet, enter an Internet domain name, such as
www.yahoo.com (216.115.108.243).If you want to look up the IP address of a website,
use the nslookup command as instructed in section 6.2.2 “Nslookup” for details.
For other operating systems running the IP protocol, you can enter the same ping
command at a command prompt or through a system administration utility.
6.2.2 Nslookup
The nslookup command is used to query the IP address associated with a domain
name. You can specify the common domain name and use the nslookup command to
look up in the DNS server (usually located though your ISP).If that name is not in your
ISP’s DNS table, the request is then sent to a higher-level server until the name is found.
The server then returns the associated IP address.
On Windows-based computer, you can execute the nslookup command from the [Start]
menu. Choose [Start/Run] and in the open text box type the following:
nslookup
Click <OK> and a command prompt window appears. The [Command Prompt –
nslookup] window is displayed with a bracket prompt (>).At the prompt, type the domain
name of the desired Website, for example www.microsoft.com.
The window displays the associated IP address as shown below.
Figure 6-3 Use the nslookup command
Some websites with heavy traffic use multiple servers to carry the same information. So
it is common to have several IP addresses associated with one Internet domain name.
To exit from the nslookup utility, enter exit.
