We pick f.root-servers.net, one of the 13 root servers (1), and ask it about e.pn and learn that pn is delegated to four name servers (2), so we ask ns2.pitcairn.net.pn where we learn that e.pn is delegated to two name servers, including ns2.mailart.com (3), so we ask that one and get the following answer:
E.pn is a domain controlled by two domain name servers at mailart.com. Both are on the same IP network. Incoming mail for e.pn is handled by one mail server at e.pn themselves. E.pn has one IP number (180.42.26.116), but the reverse is ?.
Aaa.cx, b.mu, 7.kz, dog.tc, 4.kz and at least 58 other hosts point to the same IP. O.mu, p.pn, 8.mu, r.pn, 4.kg and at least 93 other hosts share name servers with this domain. Orange.ms share mail servers under another name with this domain. Mail.e.pn are hosts under this domain. E.de, e.cc, e.coop, e.org, e.ly and at least 200 other hosts are similar domain names.
