DNS delegation of bialystok.biz updated: Jun 19, 2013 10:04:57 AM
We pick i.root-servers.net, one of the 13 root servers (1), and ask it about bialystok.biz and learn that biz is delegated to six name servers (2), so we ask b.gtld.biz where we learn that bialystok.biz is delegated to two name servers, including ns1.serwery.pl (3), so we ask that one and get the following answer:
Three of the seven host names that point only to the IP number 126.96.36.199 use the two name servers ns1 and ns2.netart.pl together (but not ns3.netart.pl ), hereafter referred to as "name server group 1". Worth noting is that three of the domains that use name server group 1 point only to the IP number 188.8.131.52.
The two name servers ns1 and ns2.netart.pl together
