Configuration procedure
# Configure a mapping between host name host.com and IP address 10.1.1.2.
<Sysname> system-view
[Sysname] ip host host.com 10.1.1.2
# Execute the ping host.com command to verify that the device can use the static domain name resolution
to get the IP address 10.1.1.2 corresponding to host.com.
[Sysname] ping host.com

Dynamic domain name resolution configuration example
Network requirements
As shown in Figure 40 , the IP address of the DNS server is 2.1.1.2/16 and the name suffix is com. The
mapping between domain name Host and IP address 3.1.1.1/16 is stored in the com domain.
Device serves as a DNS client, and uses the dynamic domain name resolution and the suffix to access the
host with the domain name host.com and the IP address 3.1.1.1/16.
