Name Servers
Two name servers handle the delegation for askdrmath.org: dns1.registrar-servers.com and dns2.registrar-servers.com.
askdrmath.org uses the same name servers as several other domains — among them getmeateam.com, saltfor.com, omarsayed.in and two more.
Some name servers delegated to askdrmath.org are also used by other domains, notably octomino.net and rathboneqi.com.
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.
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.
