How to Find DNS Servers

The easiest way to find DNS servers is by using the ‘nslookup’ tool.

• Start nslookup
• Set the search type to NS. This tells nslookup to search for nameservers
• Finally, enter the domain name for the nameservers being searched for

Here are some search examples for the most popular searches:
