We pick e.root-servers.net, one of the 13 root servers (1), and ask it about cernet.net and learn that net is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that cernet.net is delegated to two name servers, including ns2.net.edu.cn (3), so we ask that one and get the following answer:
Four of them use the name server dns.edu.cn. Worth noting is that four of the domains that use the name server dns.edu.cn point to the IP number 202.112.0.46.
The name server dns2.edu.cn
There are more than two hundred domains that use the name server dns2.edu.cn.
Nine of them point to the IP number 202.112.0.46. Worth noting is that four of the host names that point to the IP number 202.112.0.46 use the name server dns.edu.cn.
