domain name to search. The CNAME can be define to mapped to the domain name which mapped to
address, but it's not recommended to use another domain name which the CNAME correspond to.

In other words, the CNAME of host5.test.net.tw is mapped to the formal name of host23.test.net.tw.
If we ping the host5.test.net.tw in DOS, then it will shows the IP address of 61.11.11.14.
