實驗環境：公司註冊了兩個DNS地區：benet.com， accp.com。要求使用兩台RHEL5伺服器構建網域名稱系統，分別作為主、從網域名稱伺服器，其中的任一台都能解析benet.com和accp.com域的主機地址，如所示。

環境：公司註冊兩個DNS地區，benet.com accp.com

要求任意一台伺服器都能解析這兩個網域名稱

主網域服務器地址為ns1.benet.com173.16.16.5

從網域服務器地址為ns2.benet.com 173.16.16.6

Benet.com 和 accp.com地區提供以下解析記錄

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

為benet.com地區中的www mail ftp網站提供反向解析

安裝DNS的軟體包，主要都是安裝這3個包
