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
PING
Explanation: There must be a host name or IP address entered in the input box
in order for the Router to Ping.
could not test Explanation: Test could not be executed because of Router status.
