I seee...hmm. This isn't too easy in my view and may add significant load on the server. I won't do it for you but I'll give you some direction as to how I'd do it if I was really set on it.

I don't believe you can do this with one sql statement based on the current table layout. But if you add some fields perhaps it can be done. Very complicated though. There may be some code somewhere to handle this. Look in the IPAddress code of vb. The problem is you need to do recursive searching. Or try I think it's php.net for some code.

Personally I think it's way more trouble than it's worth....if you can accept .5 instead of .5 then .25 etc it will be a little bit easier with a new field, but still a royal pain.
