We pick l.root-servers.net, one of the 13 root servers (1), and ask it about facebook.lt and learn that lt is delegated to five name servers (2), so we ask e.tld.lt where we learn that facebook.lt is delegated to four name servers, including ns1.serveriai.lt (3), so we ask that one and get the following answer:
All of the more than hundred host names that point to the IP number 79.98.24.138 point only to that ip number (example: zaidimai.biz, ab.lt and ania.lt ).
The four name servers ns1, ns2, ns3 and ns4.serveriai.lt together
There are more than hundred domains that use name server group 1.
