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 CTRL_C 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

56 bytes from 10.1.1.2: icmp_seq=4 ttl=255 time=2.000 ms

Dynamic domain name resolution configuration example

Network requirements

As shown in Figure 34, the device wants to do the following:

• Access the host by using an easy-to-remember domain name rather than an IP address.

• Ask 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 DNS and the DNS suffix com on the device that serves as a DNS client. The device

can then use the domain name host to access the host with the domain name host.com and the IP

address 3.1.1.1/16.
