8.3.2 Configuring Static DNS Entries

You can create a table of mappings between domain names and IP addresses and add commonly-
used domain names to this table. When a client needs to use the IP address corresponding to a
domain name, the client can search the table for the required IP address. This improves the
efficiency of domain name resolution.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ip host host-name ip-address
The IP address corresponding to the host name is configured.
A host name corresponds to only one IP address. When you configure an IP address for a host
for several times, only the IP address configured at the latest is valid. To resolve several host
names, repeat Step 2.
You can configure a maximum of 50 static DNS entries.

8.3.3 Configuring Dynamic DNS

To perform dynamic domain name resolution, you need a special domain name resolution server,
which runs a server program. This server provides mappings between domain names and IP
addresses and receives resolution requests from the client.
