We pick h.root-servers.net, one of the 13 root servers (1), and ask it about sj-golf.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that sj-golf.com is delegated to two name servers, including ns3.01isp.com (3), so we ask that one and get the following answer:
Twelve of them use the name server ns3.01isp.com. Worth noting is that twelve of the domains that use the name server ns3.01isp.com point to the IP number 118.119.254.247.
The mail server mx603hk.now.net.cn
There are several hundred of domains that use the mail server mx603hk.now.net.cn.
