MySQL中用整数存储IP地址？

IP<==>整数
public class IpLongUtils {
    
    public static long ip2Long(String ipStr) {
        String[] ip = ipStr.split("\.");
        return (Long.valueOf(ip[0]) << 24) + (Long.valueOf(ip[1]) << 16)
                + (Long.valueOf(ip[2]) << 8) + Long.valueOf(ip[3]);
    }

    
    public static String long2Ip(long ipLong) {
        StringBuilder ip = new StringBuilder();
        ip.append(ipLong >>> 24).append(".");
        ip.append((ipLong >>> 16) & 0xFF).append(".");
        ip.append((ipLong >>> 8) & 0xFF).append(".");
        ip.append(ipLong & 0xFF);
        return ip.toString();
    }


    
    public static void main(String[] args) {
        System.out.println(ip2Long("192.168.0.1"));
        System.out.println(long2Ip(3232235521L));
        System.out.println(ip2Long("10.0.0.1"));
    }

}
