We pick f.root-servers.net, one of the 13 root servers (1), and ask it about suncoastbr.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that suncoastbr.com is delegated to four name servers, including dpns2.dnsnameserver.org (3), so we ask that one and get the following answer:
Half of the several thousand of host names that point only to the IP number 208.87.149.250 use name server group 1 (example: iclerk.org, desimud.com and siswinsuit.com ). Worth noting is that a third of the domains that use name server group 1 point only to the IP number 208.87.149.250.
The two name servers dpns1 and dpns3.dnsnameserver.org together
All of the more than two thousand domains that use name server group 2 point only to the IP number 208.87.149.250.
