That's twice now you've indicated that IP ranges are causing you some
problems. What's the big deal?

(a) If you don't have a specialised data type, just parse an IP address
into an unsigned 32-bit integer so that you can do greater/less-than
tests and masking easily

(b) handle IP range queries just like you'd do _any_ range query

Or am I missing something fundamental ? 

Cheers,
John
