I'd still much rather store something that can be indexed in a btree than something where you have to always call a function on and do full table scans. Of course, before displaying to the user you'd use long2ip again (or the database equivalent you mentioned; I usually avoid doing unnecessary computations on the database and, instead, let the application handle display logic).
