ip校验正则

最近发现有ipv4与ipv6混合的ip访问，造成校验不通过。发个帖记下

效率问题，自行考虑吧。

可以加个判断，通过 

1. ":"

2. "."

3. ":"与"."
   

三种情况进行校验判断

public class CheckIp {
private static String ip_formatv4 = "^((((\\d{1,2})|(1\\d{2})|(2[0-4]\\d)|(25[0-5]))\\.){3}((\\d{1,2})|(1\\d{2})|(2[0-4]\\d)|(25[0-5])))|()$";
private static String ip_formatv6 = "^([\\da-fA-F]{1,4}:){6}((25[0-5]|2[0-4]\\d|[01]?\\d\\d?)\\.){3}(25[0-5]|2[0-4]\\d|[01]?\\d\\d?)$|^::([\\da-fA-F]{1,4}:){0,4}((25[0-5]|2[0-4]\\d|[01]?\\d\\d?)\\.){3}(25[0-5]|2[0-4]\\d|[01]?\\d\\d?)$|^([\\da-fA-F]{1,4}:):([\\da-fA-F]{1,4}:){0,3}((25[0-5]|2[0-4]\\d|[01]?\\d\\d?)\\.){3}(25[0-5]|2[0-4]\\d|[01]?\\d\\d?)$|^([\\da-fA-F]{1,4}:){2}:([\\da-fA-F]{1,4}:){0,2}((25[0-5]|2[0-4]\\d|[01]?\\d\\d?)\\.){3}(25[0-5]|2[0-4]\\d|[01]?\\d\\d?)$|^([\\da-fA-F]{1,4}:){3}:([\\da-fA-F]{1,4}:){0,1}((25[0-5]|2[0-4]\\d|[01]?\\d\\d?)\\.){3}(25[0-5]|2[0-4]\\d|[01]?\\d\\d?)$|^([\\da-fA-F]{1,4}:){4}:((25[0-5]|2[0-4]\\d|[01]?\\d\\d?)\\.){3}(25[0-5]|2[0-4]\\d|[01]?\\d\\d?)$|^([\\da-fA-F]{1,4}:){7}[\\da-fA-F]{1,4}$|^:((:[\\da-fA-F]{1,4}){1,6}|:)$|^[\\da-fA-F]{1,4}:((:[\\da-fA-F]{1,4}){1,5}|:)$|^([\\da-fA-F]{1,4}:){2}((:[\\da-fA-F]{1,4}){1,4}|:)$|^([\\da-fA-F]{1,4}:){3}((:[\\da-fA-F]{1,4}){1,3}|:)$|^([\\da-fA-F]{1,4}:){4}((:[\\da-fA-F]{1,4}){1,2}|:)$|^([\\da-fA-F]{1,4}:){5}:([\\da-fA-F]{1,4})?$|^([\\da-fA-F]{1,4}:){6}:$";

public static String IP_FORMAT = ip_formatv4+"|"+ip_formatv6+"|" +ip_formatv46;

一种优化写法

public static boolean check_ip(String ip){
    if(patternParam(ip,ip_formatv4)|| patternParam(ip,ip_formatv46)
    ||patternParam(ip,ip_formatv6)){
        return true;
    }else {
        return false;
    }
}
