You can use zfbot.com to research domain name.
Find the name servers following the instructions here: http://anonit.blogspot.com/2015/06/to-lookup-dns-records-for-domain-name.html.
Enter the name server and enter the domain query. EG: Enter a primary name server of ‘a.ns.facebook.com’ and enter ‘facebook’ in Starts:
You can then see a list of domains that facebook has listed on their name servers.
This works with any domain. EG: nameserver ns35.domaincontrol.com and anonit.
To lookup DNS records for a domain name on Windows, you can use NSLookup.
Open a command prompt, and enter the following command: nslookup
This will give you the server that you will query and the IP address of that server.
Type the command: set q=any
This is short for set querytype=any, which will give all results, regardless of type.
Enter the domain name to query. EG: anonit.net
This will then give the results. If you fail to get the expected results, you can try using a trailing full stop at the end of the domain name, eg: anonit.net.
Additionally you can query other name servers, by using the server command. Eg: server 188.8.131.52 will set google as the DNS server to query.
