Re: RE: even more CIDR weirdness (was equality operator on CIDR colum n as primary key)

IIRC, there were some problems with CIDR where it was considering
the low bits significant even though they might not have been set
(in the case of 192.169/16 for example) which was causing fairly
odd behavior.

I believe they've routed out these problems in current sources
so it should be fixed for 7.1.
