How to Find your DNS Servers

The easiest way to find your DNS servers is by using the `nslookup` tool.

  • Start nslookup
  • Set your search type to NS -- this tells nslookup to search for nameservers
  • Finally, enter in the domain name for which you would like to find the nameservers

Here are some example searches for the most popular lookups:
