We pick e.root-servers.net, one of the 13 root servers (1), and ask it about com.tv and learn that tv is delegated to seven name servers (2), so we ask g5.nstld.com where we learn that com.tv is delegated to two name servers, including ns.email.com.cn (3), so we ask that one and get the following answer:
Eleven of them use only the mail server mail.com.tv. Worth noting is that all of the domains that only use the mail server mail.com.tv use name server group 1.
Eleven of them point only to the IP number 223.202.15.181. Worth noting is that seven of the host names that point only to the IP number 223.202.15.181 use name server group 1.
There are 15 host names that point only to the IP number 223.202.15.181.
Seven of those use name server group 1. Worth noting is that seven of the domains that use name server group 1 point only to the IP number 223.202.15.181.
