We pick h.root-servers.net, one of the 13 root servers (1), and ask it about x.wp.pl and learn that pl is delegated to eight name servers (2), so we ask c-dns.pl where we learn that wp.pl is delegated to three name servers, including ns1.wp.pl (3), so we ask that one and get the following answer:
X.wp.pl is a domain controlled by two domain name servers at wp.pl. Both are on different IP networks. Incoming mail for x.wp.pl is handled by one mail server also at wp.pl. X.wp.pl has one IP number (212.77.101.133), but the reverse is ?.
There are about twenty host names that point to the IP number 212.77.101.133.
All of those point only to that ip number (example: pro.wp.pl ).
Three quarter of them use the name server ns2.wp.pl. Worth noting is that more than one in seven of the domains that use the name server ns2.wp.pl point to the IP number 212.77.101.133.
Three quarter of them use the name server ns1.wp.pl. Worth noting is that more than one in seven of the domains that use the name server ns1.wp.pl point to the IP number 212.77.101.133.
The name server ns2.wp.pl
There are about a hundred domains that use the name server ns2.wp.pl.
More than one in seven of them point to the IP number 212.77.101.133. Worth noting is that three quarter of the host names that point to the IP number 212.77.101.133 use the name server ns2.wp.pl.
The mail server mx.wp.pl
There are more than two hundred domains that use the mail server mx.wp.pl.
