We pick k.root-servers.net, one of the 13 root servers (1), and ask it about unterkircher.com and learn that com is delegated to 13 name servers (2), so we ask e.gtld-servers.net where we learn that unterkircher.com is delegated to five name servers, including dns1.registrar-servers.com (3), so we ask that one and get the following answer:
Unterkircher.com is a domain controlled by five domain name servers at registrar-servers.com having a total of 22 IP numbers. Some of them are on the same IP network. Incoming mail for unterkircher.com is handled by five mail servers at googlemail.com and google.com having a total of 48 IP numbers. There are twelve duplicated IP numbers. Some of them are on the same IP network.
The two last resort mail servers aspmx2 and aspmx3.googlemail.com together
Most of the several thousand of domains that use last resort mail server group 1 use the primary mail server aspmx.l.google.com (example: yeahtubers.com, comexgroup.net and claritydetox.com ). Worth noting is that more than one in seven of the domains that use the primary mail server aspmx.l.google.com use last resort mail server group 1.
The primary name server dns1.registrar-servers.com only
