We pick g.root-servers.net, one of the 13 root servers (1), and ask it about gt.res.rr.com and learn that com is delegated to 13 name servers (2), so we ask k.gtld-servers.net where we learn that rr.com is delegated to five name servers, including dns1.rr.com (3), so we ask that one and learn that gt.res.rr.com is delegated to two name servers (4), so we ask dns-pri-01.texas.rr.com and get the following answer:
Gt.res.rr.com is a domain controlled by four domain name servers at rr.com. Some of them are on the same IP network. Incoming mail for gt.res.rr.com is handled by six mail servers also at rr.com having a total of two IP numbers. There are ten duplicated IP numbers. Both are on the same IP network.
