The Router has two built-in tools that will help with troubleshooting network problems.
DNS Name Lookup
The Internet has a service called the Domain Name Service (DNS), which allows users to enter an easily
remembered host name, such as www.RV082.com, instead of numerical TCP/IP addresses to access Internet
resources. The Router has a DNS lookup tool that will return the numerical TCP/IP address of a host name.
Enter the host name to look up in the Look up the name field and click the Go button. Do not add the prefix
http://, otherwise the result will be Address Resolving Failed. The Router will then query the DNS server and
display the result at the bottom of the screen. See Figure 6-25.
Note: The IP address of the DNS server must be entered in the Network Settings page for the DNS Name Lookup
feature to function.
Ping
The Ping test bounces a packet off a machine on the Internet back to the sender. This test shows if the Router is
able to contact the remote host. If users on the LAN are having problems accessing services on the Internet, try
