"3Com". Then the system connects the input domain name with the suffix into
"3Com.com" automatically to search. When the domain name suffix is used, if the input
domain name does not include ".", like "3Com", the system regards it as a host name
and add a domain name suffix to search. After all the domain names are failed to be
searched out in this way, the system finally searches with the primarily input domain
name. If the input domain name does include ".", like "www.3Com", the system
searches with it directly. The system adds each suffix to search one by one only after
the search fails. If the input domain name contains a "." in the final position, like
"3Com.com.", it indicates that the domain name suffix needs not to be added. The
system removes the last "." from the input domain name and search with the remaining
part. Succeeded or not, the system returns to the originally input domain name. Put it
more specifically, if the last character of the input domain name is ".", the system only
searches according to characters before the "." rather than matches the domain name.
In this sense, the last "." is also called "search terminator".

14.2 Configuring Static Domain Name Resolution

You can use this command to map the host name to the host IP address. When you use
applications like Telnet, you can use the host name directly, and the system translates it
into the IP address, rather than the obscure IP address.
Perform the following configuration in system view.
Table 14-1 Configure host name and the corresponding IP address

Cancel

Each host can have only one IP address. If you configure a host name more than once,
then the IP address configured at last is effective.
