DNS Server
The DNS Server test verifies that the server can look up a name
or IP address.
Test setup
The first setup screen is used to type in the IP address of the
DNS server and the name or address that will be sent to the
DNS server in the request. If no name or address is provided,
the DNS server is requested to look up its own address and
return a name.
The last setup screen provides a list of measurements
performed during the test. Select a measurement from the list
and press Edit to view and modify the thresholds used to rate the
performance of the measurement.
The following measurements are taken during the test.
PING Response The time taken to perform an ICMP Echo test
on the server.
Server Response The request or response time for converting a
name or address into an address or name.
