I want the IP address to be written at the top of the welcome message when we enter the server. Please help !

IP adress of what?

Your server?

I guess from the players connecting to the server.
Anyway, it isn't that simple to get it done in the first place and certainly not worth the effort for a demo player (no disrespect to them, but usualy nothing good comes from that group of players).

The reason, i asked what kind of IP adress he wants. Is because i checked his driven distance, which is 0. So you know what i'm talking about.

To get the players IP, isnt that simple indeed. Lapper doesnt have the insimpacket that contains the Players info.

ISP_NCI, // 57 - info : new connection - extra info for host

I have tried to add it, but it gaves me false data somehow. So i stopped with adding this packet.
