These don't always match.  For instance, if I want to find all of the 
allocations from 210.0.0.0/7 I would probably have to do a search for 
210.0.0.0/8 and 211.0.0.0/8 if those were the entries in the database. 
It's not *strictly* necessary, but we don't really have performance 
problems so I'd prefer not to limit the protocol unnecessarily.

That's possibly useful.  Unfortunately we don't have (unique) identifiers 
for network blocks except for the start/end IP.
