Reverse for a /23

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.
