We pick k.root-servers.net, one of the 13 root servers (1), and ask it about uci.cn and learn that cn is delegated to six name servers (2), so we ask d.dns.cn where we learn that uci.cn is delegated to two name servers, including ns1.uci.cn (3), so we ask that one and get the following answer:
Uci.cn is a domain controlled by two domain name servers at ucigroup.org. Both are on the same IP network. Incoming mail for uci.cn is handled by one mail server at uci.cn themselves. Uci.cn has one IP number (211.152.45.96), but the reverse is ?.
Five of them point to the IP number 211.152.45.96. Worth noting is that five of the host names that point to the IP number 211.152.45.96 use the name server ns1.ucigroup.org.
The IP number 211.152.45.96
There are eight host names that point to the IP number 211.152.45.96.
