We are doing this on some zones mostly for human use, not for rbldnsd.
In particular for the dialup DNSbls (PDL, Dynablock) I like to
see it clearly when they list a /16 or a /18, rather than 
scrolling several pages of /24's checking if any one is missing.

By the way: I can confirm now that when SBL lists some a.b.c.d/nn
network and a.b.c.d is not the base address for that network,
that is *not* a mistake but simply an expansion of a listing, 
where the original IP was kept to allow easy lookups of the problem
source.  So these records must be kept [ I am replacing
the original IP with the base address before feeding them to
rbldnsd, I don't know if this is really necessary or not .. ]
