java ipv4校验正则字符串

String IPV4_REGEX = "\A(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\z";
        List<String> list = Arrays.asList(split);
        for (String item : list) {
            if(Pattern.matches(IPV4_REGEX, item) == false){
                throw new Exception("存在不合规的ip");
            }
        }

类似于上面的IPV4_REGEX
