We pick k.root-servers.net, one of the 13 root servers (1), and ask it about ns1.fi and learn that fi is delegated to nine name servers (2), so we ask c.fi where we learn that ns1.fi is delegated to two name servers, including ns3.fi (3), so we ask that one and get the following answer:
Ns1.fi is a domain controlled by two domain name servers at ns1.fi and ns3.fi. Both are on different IP networks. Incoming mail for ns1.fi is handled by one mail server at isotalo.net. We are missing the IP:s of one server: mail.isotalo.net. Ns1.fi has one IP number (91.90.53.140), which also has a corresponding reverse pointer.
A third of the more than hundred domains that use the name server ns1.fi use the two name servers ns1 and ns2.fi together (but not ns3.fi ), hereafter referred to as "name server group 2", (example: 715517.biz, 7175.biz and alastonsuomi.co ).
The two name servers ns1 and ns2.fi together
There are about sixty domains that use name server group 2.
