DNS

The DNS test issues a request to try to resolve the name of a particular host. The host name is entered in the input box. The following is a list of the possible responses:

	DNS
Success	The Router has successfully obtained the resolved address. The IP address is
	shown below the host name input box
No Response	Explanation: The Router has failed to successfully obtain the resolved address.
	Solution: Determine the IP addresses of your DNS servers (from the home page,
	click "Edit" and then "Advanced"), and then use the Ping test near the bottom of
	the Diagnostic screen to try to Ping those addresses. This may provide useful
	information when you contact your service provider and speak with Technical
	Support.
Host not found	Explanation: The DNS Server was unable to find an address for the given host
	name.
	Solution: That host may no longer be available on the Internet. Try entering a
	different host name.
No data, enter host name	Explanation: There must be a host name entered in the input box.
could not test	Explanation: Test could not be executed because of Router status.

PING

Select PING to check IP continuity to a remote computer either within or beyond the Service Providers network.

Enter either the IP address or the hostname of the remote host computer into the input box to the right of the Test button. If you Ping by name, DNS will be used to look up the appropriate IP address for that name.

The following is a list of the possible responses:

	PING
Success	The Remote Host Computer was detected.
No Response	Explanation: This message will occur when there was no response to the Ping
	from the remote computer.
	Solution: Bear in mind that many hosts on the Internet are configured for
	security reasons to not respond to IP Ping messages. If you get a success from
	the DNS test using the same host name, chances are good that your connection
	is fine, whether you can Ping the named host or not.
No name or address to	Explanation: There must be a host name or IP address entered in the input box
PING	in order for the Router to Ping.
could not test	Explanation: Test could not be executed because of Router status.
