III. 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 static domain
name resolution to get the IP address 10.1.1.2 corresponding to host.com.
[Sysname] ping host.com
PING host.com (10.1.1.2): 56 data bytes, press CTRL_C to break

1.4.2 Dynamic Domain Name Resolution Configuration Example
I. Network requirements
As shown in Figure 1-3, the switch serving as a DNS client uses dynamic domain name
resolution to access the host at 3.1.1.1/16 through its domain name host. The DNS
server has the IP address 2.1.1.2/16. The DNS suffix is com.
