ip4zone.com.
(ns1,ns2).attwc.com.
We pick c.root-servers.net, one of the 13 root servers (1), and ask it about ns1.ip4zone.com and learn that com is delegated to 13 name servers (2), so we ask k.gtld-servers.net where we learn that ip4zone.com is delegated to two name servers, including ns1.attwc.com (3), so we ask that one and get the following answer:
Three of them point only to the IP number 64.71.160.235.
Three of them use only the IPv4 number 64.71.160.235. Worth noting is that two of the domains that only use the IPv4 number 64.71.160.235 use only the name server ns1.ip4zone.com.
The IPv4 number 64.71.160.235 only
All of the three domains that only use the IPv4 number 64.71.160.235 are under the tld "com".
The primary name server ns1.ip4zone.com only
Four of the seven domains that use the primary name server ns1.ip4zone.com use only the name server ns1.ip4zone.com. Worth noting is that all of the domains that only use the name server ns1.ip4zone.com use the primary name server ns1.ip4zone.com.
