Network requirements

As shown in Figure 44, the device wants to access the host by using an easy-to-remember domain name 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.
