Hello!
Is there any option to ban annoying player with changing ip adress on his mac adress?

well you could ban by name... but names can be changed. You can ban an entire area, but that puts out a few people... there might be a way to combine them though

ban a range.

It depends what the nature of his IPs are. Do they all look similar? Do they all start with a similar set of numbers? If so, then a rangeban is your best choice. If not, then you might either have to ban multiple ranges or you simply might not be able to successfully keep him out. If that's the case, then (assuming your server is synced up to an IRC channel, which if it's not you should do) put his name on your highlights so that it alerts you whenever he joins the game. Note that as far as I know, this is only doable (the highlight part) with IRC clients, so if you don't have one of those then I suggest you go download one.

I've already created script to ban on name, but he change his name :/
His ip change not only XX.***(...), but **.**(...), what is a big problem.
I will see maybe he has ip like XX.XXX.**(..) and YY.YYY.*(...) if he has then i create ban range ip script.
