registrion block on IP adres
 

Is there a way to block people from registration to our board which have a specified IP-adres or ip-range.

if so how can i do this.

There's Settings -> Options -> User Banning Options -> Banned IP Addresses in the adminCP. But that's supposed to block access to the entire board, not just registration.

Really, if you need to block an IP range you should do it at the server level. e.g. We use Cpanel.

Be very careful though, as you will be blocking a whole lot of people.
