通過使用view使不同區域的用戶看的試圖不一樣，不同區域的用戶對應的數據庫文件不一樣，爲每一種不同的客戶來源定義一條個性化的DNS解析記錄。 使他們之間訪問的IP地址不同。

Stopping named: . [ OK ]
Starting named: [ OK ]
[root@www named]# chkconfig named on

也可以只在named.conf文件裏定義倆個區域
[root@www etc]# vim named.conf
view cache1 {
match-clients { 192.168.10.0/24; };
recursion yes;
match-destinations { any; };
zone "abc.com" IN {
type master;
file "cache1.db";
};
#include "/etc/named.rfc1912.zones";
};
view cache2 {
match-clients { 192.168.40.0/24; };
recursion yes;
match-destinations { any; };
zone "abc.com" IN {
type master;
file "cache2.db";
};
[root@www etc]# vim named.rfc1912.zones –文件裏不用再聲明區域
[root@www etc]# service named restart
[root@www etc]# rndc flush
[root@www etc]# nslookup www.abc.com
