Name Servers

Two name servers handle the delegation for opmath.com: dns1.registrar-servers.com and dns2.registrar-servers.com.

opmath.com shares its NS records with other domains, for example littlemonstercompany.com, shanimuni.net, booksvc.com and two others.

opmath.com has overlapping name servers with several other domains — among them darbypayne.com, deeplearning.online, 1ltd.org and mysidehustlesecrets.com.

The name servers dns3.registrar-servers.com, dns4.registrar-servers.com and dns5.registrar-servers.com are commonly seen alongside these name servers.

dns1.registrar-servers.com and dns2.registrar-servers.com both carry two IP addresses. The A records for dns1.registrar-servers.com are 156.154.132.200 and 2610:a1:1024::200; the A records for dns2.registrar-servers.com are 156.154.133.200 and 2610:a1:1025::200.

These mail servers tend to appear in combination with mail servers alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and 3 others.

Host names that have two IP addresses:
