Re: [TCLUG:21021] dns mx question

[Adam Maloney <adamm@sihope.com>]

You could try setting up your machine to be a slave for the zone.  It
would still carry authorative information so it wouldn't have to do a
lookup every time...you'd just have to do a lookup when Bind wanted to
update the zone from the primary.

zone "hearing.org" {
	type slave;
	file "sec/hearing.org";
	masters {
		primary.dns.server
	};
};
