You should ask them to upgrade; 7.4 is getting pretty old.

I'm pretty sure PostgreSQL won't be able to use any indexes for this
(EXPLAIN ANALYZE would verify that). Instead, expand the between out:
WHERE ipfrom >= '...' AND ipto <= '...'
Also, generally speaking, databases and CamelCase don't mix too well;
you'll probably be happier doing something like ip_from and ip_to.
