Lab environment: the company has registered two DNS regions: benet.com and accp.com. Two RHEL5 servers are required to build a domain name system, which serves as the master and slave domain name servers respectively. Either of them can resolve the host addresses of the benet.com and accp.com domains, as shown in.

Environment: The company registers two DNS regions, benet.com accp.com

The two domain names must be resolved by any server.

The master Domain Server address is ns1.benet. com173.16.16.5.

The slave Domain Server address is ns2.benet.com 173.16.16.6.

The Benet.com and accp.com regions provide the following resolution records:

Mail. benet. com123.45.67.89, ftp.benet.com 123.45.67.90

Www.benet.com 123.45.67.88, * .benet.com 123.45.67.90

Www.accp.com 58.109.87.65 forum.accp.com 58.109.87.66

Provides reverse resolution for www mail ftp sites in the benet.com Region
