Get the players registered ip

pawn Код:

new tmp2[56], tmp3[56];

GetPlayerIp(blabla, tmp3);
dini_Int(blabla, tmp2);

If(strcmp(tmp2, tmp3 = true))
{
   IsPlayerLogged[playerid] = 1;
   SendClientMessage(playerid, blue, "You've been automaticly logged in");
}

Something like that, thats what i would do
