We pick h.root-servers.net, one of the 13 root servers (1), and ask it about athea.us and learn that us is delegated to six name servers (2), so we ask e.cctld.us where we learn that athea.us is delegated to two name servers, including ns76.domaincontrol.com (3), so we ask that one and get the following answer:
Athea.us is a domain controlled by two domain name servers at domaincontrol.com having a total of four IP numbers. All four of them are on different IP networks. Incoming mail for athea.us is handled by two mail servers at secureserver.net having a total of three IP numbers. There are three duplicated IP numbers. Two of them are on the same IP network. Athea.us has one IP number (68.178.232.100), but the reverse is ?.
The two name servers ns75 and ns76.domaincontrol.com together
There are several thousand of domains that use name server group 1.
Most of those use the two mail servers mailstore1 and smtp.secureserver.net together, hereafter referred to as "mail server group 1", (example: andrewvip.info, latogallc.com and htauto1.org ). Worth noting is that one percent of the domains that use mail server group 1 use name server group 1.
