We pick h.root-servers.net, one of the 13 root servers (1), and ask it about e.shaneco.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that shaneco.com is delegated to five name servers, including ns5.savvis.net (3), so we ask that one and get the following answer:
E.shaneco.com is a domain controlled by five domain name servers at savvis.net. Two of them are on the same IP network. Incoming mail for e.shaneco.com is handled by two mail servers at mxlogicmx.net and mxlogic.net having a total of five IP numbers. There are two duplicated IP numbers. Some of them are on the same IP network.
The three name servers ns1, ns2 and ns3.savvis.net together
Twelve percent of the more than two thousand domains that use name server group 3 point only to the IP number 216.34.132.16 (example: ripfireburn.com ).
The five name servers ns1, ns2, ns3, ns4 and ns5.savvis.net together
Eight percent of the several thousand of domains that use name server group 1 point only to the IP number 165.193.220.121.
