We pick a.root-servers.net, one of the 13 root servers (1), and ask it about tld.ee and learn that ee is delegated to eight name servers (2), so we ask ns.eenet.ee where we learn that tld.ee is delegated to four name servers, including c.tld.ee (3), so we ask that one and get the following answer:
Tld.ee is a domain controlled by four domain name servers at aso.ee and tld.ee having a total of six IP numbers. Two of them are on the same IP network. Incoming mail for tld.ee is handled by one mail server at tld.ee themselves. Tld.ee has one IP number (18.104.22.168), but the reverse is whois.tld.ee.
All of the three host names that point to the IP number 22.214.171.124 point only to that ip number.
The three name servers b, c and d.tld.ee together
All of the three domains that use the three name servers b, c and d.tld.ee together, hereafter referred to as "name server group 1", point only to the IP number 126.96.36.199 (example: eestiinternet.ee ).
The name server b.tld.ee
Three of the five domains that use the name server b.tld.ee use name server group 1.
The name server ans1.aso.ee
There are several thousand of domains that use the name server ans1.aso.ee.
