III. Configuring the DNS Domain Name Searching List
Some of the websites that you access may have the same domain name, such as
sina.com.cn, huawei.com.cn, and sohu.com.cn.
To facilitate website searching of users, you can set a domain name to com.cn for
example. Thus, to search for the IP address mapped with "sina.com.cn", a user only
needs to enter the command ping sina. If no response is received, the DNS client
sends a request to query the IP address mapped with "sina".
You can configure a DNS domain name searching list by using the following command
