Analysis
Name Servers
askdrmath.com is served by two delegated name servers, dns1.registrar-servers.com and dns2.registrar-servers.com.
askdrmath.com shares its NS records with other domains, for example gumnit.com, alnooralive.com, temyventures.com and two others.
There is at least partial name server overlap between askdrmath.com and other domains — firstmindtechnologies.com, duraversion.com, fivesly.com and two more among them.
The name servers dns3.registrar-servers.com, dns4.registrar-servers.com and dns5.registrar-servers.com are often found in combination with these name servers.
Each of the two host names carries two IP addresses: dns1.registrar-servers.com points to 156.154.132.200 and 2610:a1:1024::200, and dns2.registrar-servers.com points to 156.154.133.200 and 2610:a1:1025::200.
