resolution to visit host 1 with IP address 3.1.1.1/16. The DNS Server has IP address
2.1.1.2/16. The DNS suffixes are com and net.

Note:
Before doing the following configuration, make sure the route between the router and
host 1 is reachable, and configurations are done on both devices. The IP address of
each interface is shown on Figure 1-2. Make sure the DNS Server works well and has a
mapping between host 1 and IP address 3.1.1.1/16.
