Set up a dynamic dns server with bind9.2.4 on Soalris10

Soalris10 uses bind9.2.4 to set up a dynamic dns server-Linux Enterprise Application-Linux server application information. The following is a detailed description. The view function of bind 9 is used to parse different addresses by IP address.

Dns server address: dns.test.com 192.168.0.211
Web server address: www.test.com 192.168.0.100 192.168.0.200
China Telecom address: 192.168.0.210 resolved to 192.168.0.100
China Netcom address: 192.168.0.213 resolved to 192.168.0.200

The dns PTR record cannot be missing. Otherwise, an error message will be prompted when the client uses the nslookup command for query:
** Can't find server name for address 192.168.0.211: Non-existent domain
* ** Default servers are not available
Default Server: UnKnown
Address: 192.168.0.211
The Correct prompt is:
Default Server: dns.test.com
Address: 192.168.0.211
