1.3.2 DNS Configuration Example
I. Network requirements
As shown in Figure 1-2, the switch serving as a DNS Client uses the dynamic domain
name resolution feature to access the host with the domain name being host1 and the
IP address being 3.1.1.1/16. The DNS Server has the IP address 2.1.1.2/16. The DNS
suffixes are com and net.
