We pick c.root-servers.net, one of the 13 root servers (1), and ask it about bwave.pl and learn that pl is delegated to eight name servers (2), so we ask e-dns.pl where we learn that bwave.pl is delegated to three name servers, including pubns2.tiktalik.com (3), so we ask that one and get the following answer:
Bwave.pl is a domain controlled by three domain name servers at tiktalik.com having a total of four IP numbers. Two of them are on the same IP network. Incoming mail for bwave.pl is handled by two mail servers at bwave.pl themselves. Both are on the same IP network. Bwave.pl has one IP number (37.233.98.116), but the reverse is www.tiktalik.p2.tiktalik.com.
