ns3.com.
(ns1,ns2).domaindiscover.com.
We pick l.root-servers.net, one of the 13 root servers (1), and ask it about ns3.com and learn that com is delegated to 13 name servers (2), so we ask c.gtld-servers.net where we learn that ns3.com is delegated to two name servers, including ns1.domaindiscover.com (3), so we ask that one and get the following answer:
The two name servers ns1 and ns2.domaindiscover.com together
There are several thousand of domains that use name server group 1.
Three quarter of those use mail server group 1 (example: mexicanjumpingbeans.com, yourvet.com and exp-vacs.com ). Worth noting is that three quarter of the domains that use mail server group 1 use name server group 1.
The two mail servers mx1 and mx2.daemonmail.net together
There are several thousand of domains that use mail server group 1.
Three quarter of those use name server group 1 (example: nakedsword.tv, ledgix.com and workingspaces.net ). Worth noting is that two thirds of the domains that use name server group 1 use mail server group 1.
