I don't think this operation makes much sense. Adding an integer makes some sense, but I think the original problem would be better solved by having a set returning function generate the possible network addresses to be allocated and store that set in a table. I don't think assuming everthing is a /24 is a good idea. If wrapping is to be done, there should be some mask specified. ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
