Dynamic Domain Name Resolution Configuration Example
Network requirements
As shown in Figure 1-3 , the switch serving as a DNS client uses dynamic domain name resolution to
access the host at 3.1.1.1/16 through its domain name host. The DNS server has the IP address
2.1.1.2/16. The DNS suffix is com.
