Name Servers
mastool.com uses two name servers for its delegation: dns1.registrar-servers.com and dns2.registrar-servers.com.
The name server configuration of mastool.com is shared with other domains, for instance vinciworld.xyz, robsaum.info, sixtyoneten.com and two others.
There is at least partial name server overlap between mastool.com and other domains — malterra.org, aspkin.me, peckeration.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.
The two host names dns1.registrar-servers.com and dns2.registrar-servers.com each have a pair of IP addresses: dns1.registrar-servers.com has 156.154.132.200 and 2610:a1:1024::200, and dns2.registrar-servers.com has 156.154.133.200 and 2610:a1:1025::200.

At least some of the mail servers used by mastool.com are shared with other domains: mckinseydesignindex.com, allamericanhousinggroup.com, 182web.com and two others among them.
These mail servers often appear in conjunction with the mail servers eforward4.registrar-servers.com, eforward5.registrar-servers.com, eforward6.registrar-servers.com and eforward7.registrar-servers.com.
