Right now it is ordered in the order of the colums. So if you want to sort on ip's, just drag that column to the beginning. The routine works all the way so it's sorted on the 1st collumn. IF those are the same, the 2nd column is evaluated, etc etc.
Oh, cool! Never mind, then, that does what's needed. The only thing that might make it nicer is to allow reverse-sorting, for example to put most-active servers (most users) at the top. But leave that for much later, after the bugs get shaken out.
