I am searching for a mod that will search IP addresses for my current members and will match them.

I am trying to cut down on people who already have a user name on my message board and trying to create a new user names.

Say for instance, Johndoe already has a user name and he has the following IP addresses when he has posted (11.111.111.111,11.111.111.112 ). Johndoe tries to register for another user name and after he registers the mod does a check if he is already a member. if he is a member, it will send an email or PM to me and lists what user name he already has?

Is there anything like this?

Thanks!
