DNS Lookup

DNS Lookup is a tool which looks up names from a Domain Name Server. It shows you the IP address for a domain name. It also shows you information about the name servers for a domain. When there is a problem on the network, one cause is that the DNS server is not providing the right IP addresses for your servers. You can use this utility to verify that your DNS server is returning the correct addresses for your own servers. You can also use it to verify that it is able to lookup the addresses for external domains.

The DNS Lookup form provides a gateway to the standard nslookup program. It will send the request to the DNS server entered in the "DNS Address" text box. Alternately, it will display the IP address for the host name entered in the "Host Name" text box. Clicking the DNS Lookup button initiates the test. The results of the DNS lookup are displayed in the lower portion of the page.
