Dynamic domain name resolution configuration example
Network requirements
As shown in Figure 43, configure the DNS server to store the mapping between the host's domain
name host and IPv4 address 3.1.1.1/16 in the com domain. Configure dynamic IPv4 DNS and the
DNS suffix com on the device so that the device can use the domain name host to access the host.

Configuration procedure
Before performing the following configuration, make sure that:
• The device and the host can reach each other.
• The IP addresses of the interfaces are configured as shown in Figure 43.
