1. IP v4 校验

public static boolean isboolIp(String ipAddress) {
        String ip = "([1-9]|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])(\\.(\\d|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])){3}"; 
        Pattern pattern = Pattern.compile(ip);
        Matcher matcher = pattern.matcher(ipAddress);
        return matcher.matches();
    }

2.IP v6 校验

public static void isboolIpv6(String ipAddress) {    
    String re = "^([0-9a-fA-F]{1,4}:){7}[0-9a-fA-F]{1,4}$";
    return ipAddress.matches(re);
  }
