Show player's IP when they connect to your server

This should only appear in the console or only show admins. It helps because sometimes people will reconnect with alternate accounts if you ban them while they are not on the server. This is because when you ban while they are offline the server doesn't ban the IP, only the username. Although there isn't a command to ban someone's IP you can manually put it in the blacklist.cfg file( which is something I would do ). Another way to combat this problem would be to allow the ban command to remember the player's last connected IP. Maybe even add a /banip command.... I know that this has a couple different suggestions but they are all there to combat the same issue :\

Thanks for reading and please post your opinion :D

 

thats only if they are kicked/banned while they are on the server... some people will grief then leave and there is no way to get their IP
