We pick a.root-servers.net, one of the 13 root servers (1), and ask it about bud.hu and learn that hu is delegated to seven name servers (2), so we ask c.hu where we learn that bud.hu is delegated to two name servers, including ns0.bud.hu (3), so we ask that one and get the following answer:
All of the two host names that point to the IP number 195.70.41.250 point only to that ip number.
The two name servers ns0.bud.hu and ns.euroweb.hu together
There are one domains that use the two name servers ns0.bud.hu and ns.euroweb.hu together, hereafter referred to as "name server group 2".
All of those use the two mail servers mx1 and mx2.bud.hu together, hereafter referred to as "mail server group 2". Worth noting is that all of the domains that use mail server group 2 use name server group 2.
All of them point only to the IP number 195.70.41.250.
The two mail servers mx1 and mx2.bud.hu together
There are one domains that use mail server group 2.
All of those use name server group 2. Worth noting is that all of the domains that use name server group 2 use mail server group 2.
