dns 域与acl说明

view dev-a {
        match-clients {key dev-a-key; dev-a;};
        recursion yes;
        zone "." IN {
                type hint;
                file "named.ca";
        };
        include "/etc/named.dev-a";
        include "/etc/named.rfc1912.zones";
        include "/etc/named.root.key";
};
view test-a {
        match-clients {key test-a-key; test-a;};
        recursion yes;
        zone "." IN {
                type hint;
                file "named.ca";
        };
        include "/etc/named.test-a";
        include "/etc/named.rfc1912.zones";
        include "/etc/named.root.key";
};

域、acl对应关系说明：

域：dev-a，test-a

acl：dev-a，test-a

域与acl为一对多关系，一个域可以有多条acl，但条acl只能有一个域
