$ip2id= round(rand(600000, 2550000) / 10000); //The first method is to directly generate
$ip3id= round(rand(600000, 2550000) / 10000);
$ip4id= round(rand(600000, 2550000) / 10000);
//The following is the second method, randomly select from the following data
$arr_1 = array("218","218" ,"66","66","218","218","60","60","202","204","66","66","66","59"," 61","60","222","221","66","59","60","60","66","218","218","62","63" ,"64","66","66","122","211");
$randarr= mt_rand(0,count($arr_1)-1);
$ip1id = $arr_1[ $randarr];
echo $ip1id;
