Thread:Project:Support desk/Banning a troll who changes his IP address

I don't know anything about changing an IP address, so I don't know how hard it is. I recently used $wgAccountCreationThrottle to only allow one account to be created per IP address per day, but I know he just changes his IP address since I check the box for blocking it each time I've banned one of his accounts. I haven't actually tested this configuration yet, since account creation has been prevented since I've implemented it.

Could anyone explain to me how hard it is to changed an IP address, since I'm wondering how much this will slow him down.

Also, I'm wondering if I could use a range block to keep him from editing with any new accounts he creates. That would probably only work if new IP addresses can only be created within a certain range.

Where do I go to find the IP address of a user?
