Master/Slave

[Michael De Roover]

One of the things you may want to look into, is the notions of "acl" and 
"masters". These are sections in named.conf that you can give names, that can 
be referenced elsewhere. Below is one such config I have in my own systems 
(with IP addresses partially redacted):

// Access Control Lists
// Source: https://www.zytrax.com/books/dns/ch7/acl.html
acl admin {
	192.168.##.#;
};
acl internal {
	admin;
	192.168.##.#;
	192.168.##.#;
	192.168.##.#;
};
acl external {
	admin;
	192.168.##.#;
	192.168.##.##;
	192.168.##.##;
};

// Masters
// Source: https://www.zytrax.com/books/dns/ch7/masters.html
masters satellite {
	192.168.##.#;
};

Hope this helps.
