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 device can use static domain name resolution to
resolve domain name host.com into IP address 10.1.1.2.
[Sysname] ping host.com
Ping host.com (10.1.1.2): 56 data bytes, press escape sequence to break
56 bytes from 10.1.1.2: icmp_seq=0 ttl=255 time=1.000 ms
56 bytes from 10.1.1.2: icmp_seq=1 ttl=255 time=1.000 ms
56 bytes from 10.1.1.2: icmp_seq=2 ttl=255 time=1.000 ms
56 bytes from 10.1.1.2: icmp_seq=3 ttl=255 time=1.000 ms

Dynamic domain name resolution configuration example

Network requirements
As shown in
rather than an IP address, and to request the DNS server on the network for an IP address by using
dynamic domain name resolution. The IP address of the DNS server is 2.1.1.2/16 and the DNS server has
a com domain, which stores the mapping between domain name host and IP address 3.1.1.1/16.
Configure dynamic domain name resolution and the domain name suffix com on the device that serves
as a DNS client so that the device can use domain name host to access the host with the domain name
host.com and the IP address 3.1.1.1/16.
