We pick g.root-servers.net, one of the 13 root servers (1), and ask it about h.ua and learn that ua is delegated to six name servers (2), so we ask pch.ns.ua where we learn that h.ua is delegated to three name servers, including ns3.advon.info (3), so we ask that one and get the following answer:
H.ua is a domain controlled by two domain name servers at advon.info. Both are on the same IP network. Incoming mail for h.ua is handled by five mail servers at googlemail.com, google.com and h.ua having a total of 43 IP numbers. There are eight duplicated IP numbers. Some of them are on the same IP network. We are missing the IP:s of one server: alt2.aspmx.l.google.com.h.ua. H.ua has one IP number (93.170.27.42), but the reverse is ?.
H.ua is hosted on a server in Czech Republic even though the hostname implies Ukraine.
The name server ns2.advon.info
There are eleven domains that use the name server ns2.advon.info.
All of those use the two name servers ns1 and ns2.advon.info together.
Seven of them point to the IP number 93.170.27.42. Worth noting is that seven of the host names that point to the IP number 93.170.27.42 use the name server ns2.advon.info.
The IP number 93.170.27.42
There are about twenty host names that point to the IP number 93.170.27.42.
Seven of them use the name server ns2.advon.info. Worth noting is that seven of the domains that use the name server ns2.advon.info point to the IP number 93.170.27.42.
Seven of them use the name server ns1.advon.info. Worth noting is that seven of the domains that use the name server ns1.advon.info point to the IP number 93.170.27.42.
