GetPlayerIp(playerid, IP, sizeof(IP));

In this line you are just getting your own IP adress..?
I don't think you even need this line of code.

CMD:oipcheck(playerid, params[])
{
    new playerb[32], playerbb, file[32], IP[16], string[128];
    if(!IsPlayerLoggedIn(playerid)) return SendClientMessage(playerid, COLOR_GREY, "You need to login first before using any command.");
    if(PlayerInfo[playerid][pAdmin] < 1) return SendClientMessage(playerid, COLOR_GREY, "You are not authorized to use this command.");
    if(sscanf(params, "s", playerb)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /oipcheck [playerid]");
    format(file, sizeof(file), "users/%s.ini", playerb);
    if(!dini_Exists(file)) return SendClientMessage(playerid, COLOR_GREY, "Player name not found.");
    format(PlayerInfo[playerid][pIP], 16, "%s", dini_Get(file, "IP"));
    format(string, sizeof(string), "Name: %s | IP: %s", playerbb, PlayerInfo[playerid][pIP]);
    playerb[24] = playerbb;
    SendClientMessage(playerid, COLOR_ORANGE, string);
    return 1;
