(ns14,ns7).zoneedit.com.
We pick m.root-servers.net, one of the 13 root servers (1), and ask it about dixonz.com and learn that com is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that dixonz.com is delegated to two name servers, including ns14.zoneedit.com (3), so we ask that one and get the following answer:
Dixonz.com is a domain controlled by two domain name servers at zoneedit.com. Both are on different IP networks. Incoming mail for dixonz.com is handled by five mail servers at googlemail.com and google.com having a total of 46 IP numbers. There are 16 duplicated IP numbers. Some of them are on the same IP network.
