PHP IP address truncated in loop

I have a MySQL table that contains IP addresses: Table IP addresses

When I loop the addresses in PHP, they'll be truncate:

string(3) "192"

string(3) "192"

string(3) "192"

string(2) "80"

My code: public function getListaIndirizzi(Request $request) {

    // Paginazione
    if (!$request) {
        $validator = Validator::make($request->all(), [
                    "indirizzo1" => "ip",
                    "indirizzo2" => "ip"
        ]);

        if ($validator->fails()) {
            return redirect()->back()->withInput()->withErrors($validator);
        }

        $indirizzi = IP::whereBetween("IP", [$request->get("indirizzo1"), $request->get("indirizzo2")])->paginate(10);
    } else {
        $indirizzi = IP::paginate(10);
    }

    for($i =0; $i < count($indirizzi); $i++) {
        LogController::debug((string)($indirizzi[$i]["IP"]));
    }
    die;

    return view("lista_indirizzi", ["indirizzi" => $indirizzi]);
}

I use Laravel framework
