I didn't get what you actually mean, but I hope you're trying to code '/ip [playerid]'. Well here's one with zcmd and sscanf2.

pawn Код:

CMD:ip(playerid, params[])
{
 new p2;
 if(sscanf(params, "r", p2)) return SendClientMessage(playerid, 0xFF0000FF, "Usage: /ip [playerid]");
 if(p2 == INVALID_PLAYER_ID) return SendClientMessage(playerid, 0xFF0000FF, "Player is offline.");
 new ip[16];
 GetPlayerIp(p2, ip, sizeof(ip));
 new str[128], Lname[MAX_PLAYER_NAME];
 GetPlayerName(p2, Lname, sizeof(Lname));
 format(str, sizeof(str), "%s's IP:%d", Lname, ip);
 SendClientMessage(playerid, 0xFF0000, str);
 return 1;
}

Edit:late.
