Yes, you are right. That's why I'm going with the original
First, thanks, your suggestion worked.
To my surprise, it was enough to add "limit 1" to the original query.
So:
select * from blocks,locations where locations.locid = blocks.locid AND ? >=
blocks.startIpNum AND ? <= blocks.endIpNum limit 1
takes about 1.398-005 seconds
