How can I see IP address?

[katana]

:-\ In the user list I cannot display the IP address which identify the user.
Administrator can banning a user by IP address but I dunno how I see it.
Thanks to everyone.

From the admin panel, realtime monitor window, you can see user's ip address and his country.

we'll add a function in the chat lobby to check the user's ip, then it will be more user friendly,
