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
# Use the ping host.com command to verify that the Switch can use static domain name resolution to
resolve domain name host.com into IP address 10.1.1.2.
[Sysname] ping host.com

Dynamic Domain Name Resolution Configuration Example
Network requirements
As shown in Figure 9-4 , 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.
Dynamic domain name resolution and the domain name suffix are configured on the Switch that
serves as a DNS client, and thus the Switch can use domain name host to access the host with the
domain name host.com and the IP address 3.1.1.1/16.
