the domain name "h3c.com", he can configure the "com" in the suffix list and input
"H3C". Then the system connects the input domain name with the suffix into "h3c.com"
automatically to search. When the domain name suffix is used, if the input domain
name does not include ".", like "H3C", 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.H3C", 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 "h3c.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".
6.2 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 6-1 Configure host name and the corresponding IP address
Configure
corresponding IP address
Cancel host name and the corresponding
IP address
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.
