Is there a way to manually add an IP address to a user?
what is the actual purpose of it ? as you know, in general IP address is based on user's location
I think a banned user has logged in with another IP. I want to track it to be sure.
do you mean banned user registered another account and posting on your forum ?
you have to check the IPs to find out such users.
you may try using
xemBanCookie plugin (I'm not sure of its performance)
