Static domain name resolution configuration example
Network requirements
As shown in Figure 38, Router wants to access the host by using an easy-to-remember domain name
rather than an IP address.
Configure static domain name resolution on Router so that Router can use the domain name host.com to
access the host whose IP address is 10.1.1.2.
