  • 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:

    Finding the Lincsat DNS Servers

    $ nslookup
    > set type=ns
    > lincsat.com
    Server: 66.37.143.12
    Address: 66.37.143.12#53

    Non-authoritative answer:

    lincsat.com nameserver = ns1.anywarenetworks.com.
