DNS (DNS lookup)

DNS (Domain Name System) — distributed database that is able to
determine an IP address of a network host upon a request with the host’s
domain name. DNS lookup feature allows to detect errors in NS-servers
operation. This feature is not available in the basic configuration and
should be ordered additionally.

DNS lookup test is performed for specified domain name. If requested IP
address cannot be retrieved, all bits in IP address will be set to null.

Host: Enter the name of the host of which the IP address is to be
determined.

IP: Display the IP address of the host.
