Reverse for a /23

[Stephen Amadei]

O.K... I haven't been able to get ahold of a up to date Cricket book...
(mine is revision 1) and I have read RFC2317... but I am still having
nothing but problems doing reverse for a supernet... in this case, a /23.

I am feeling really stupid and need someone to explain this to me step by
step... ;-)

I am running BIND 8.1.2 and lets say I am trying to set up reverse for
192.168.218.0/23 (192.168.218.0/24 and 192.168.219.0/24).

I put in my named.conf:

zone "218/23.168.192.in-addr.arpa" {
	type master;
	file "db.192.168.218";
};

And I put in db.192.168.218:

218/23.251.204.in-addr.arpa.	IN SOA ns.our.net someone.our.net (
				1999121701	;Serial
				10800		;Refresh after 3 hours
				3600		;Retry after 1 hour
				604800		;Expire after 1 week
				86400	)	;Minimum TTL of 1 day

218/23.251.204.in-addr.arpa.	IN NS	ns.our.net.
218/23.251.204.in-addr.arpa.	IN NS	ns2.our.net.

1.218.251.204.in-addr.arpa.	IN PTR	blah.our.net.
129.218.251.204.in-addr.arpa.	IN PTR	blah2.our.net.
1.219.251.204.in-addr.arpa.	IN PTR	blah3.our.net.
22.219.251.204.in-addr.arpa.	IN PTR	blah4.our.net.

When I HUP BIND, it just gets all upset and drops the whole zone.

Maybe I've read RFC2317 totally wrong, but the bottom line is I'm confused
over the whole situation.
