  o'reilly DNS and BIND.

  cakewalk; you'll come out of it with no more confusion at all.

  already answered by someone, but again, /var/named/master is a sensible
  target.

zone "1.168.192.in-addr.arpa" IN {
	type master;
	file "master/db.1.168.192";
};

zone "wired" IN {
	type master;
	file "master/db.wired";
};

  put these, as a suggestion, under the "// Master zones" section of the 
  default named.conf, because the heading is already there, so you might
  as well take advantage of it <G>.

  the /var/named/etc/named.conf that comes in openbsd is good to go
  as a local caching resolver.  just start it.  it will recurse/resolve
  for you anything you ask it(or at least try to).

  it will only answer queries from ::1 and 'localnets'.  localnets is
  referenced in the html on your filesystem i point to below, just read the
  'acl statement grammar' section.  as long as you have pf filtering
  queries from the world (which, if you're just using this as a 
  caching resolver and locally-authoritative-only server, is probably
  what you're doing), you're set.

  only if you're using forward zones, which the default openbsd named.conf
  does not.  anyone saying that you have to do that is hopefully talking
  about a different OS.

  bah, screw djb.

  use software in base before software in ports; use software in ports 
  before software not in base or ports.  exceptions for good reasons
  are of course, exceptions. but someone who just wants to "turn on some
  DNS for their LAN" doesn't have a good reason to use (DNS) software which
  is wholly unsupported in the (s/the/this) community.
