We pick a.root-servers.net, one of the 13 root servers (1), and ask it about jingwuyou.com and learn that com is delegated to 13 name servers (2), so we ask e.gtld-servers.net where we learn that jingwuyou.com is delegated to two name servers, including ns20.xincache.com (3), so we ask that one and get the following answer:
Jingwuyou.com is a domain controlled by two domain name servers at xincache.com having a total of two IP numbers. There are two duplicated IP numbers. Both are on the same IP network. Incoming mail for jingwuyou.com is handled by seven mail servers at google.com and jingwuyou.com having a total of 44 IP numbers. There are nine duplicated IP numbers. Some of them are on the same IP network. We are missing the IP:s of three servers: new5.jingwuyou.com, new3.jingwuyou.com and new4.jingwuyou.com.
