refer this document IP validation

请参阅本文档 IP 验证

here he has used jqueryvalidator.js and explained with example.

在这里他使用了 jqueryvalidator.js 并用示例进行了解释。

 $.validator.addMethod('IP4Checker', function(value) {
            var ip = "^(?:(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\.){3}" +
                "(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)$";
                return value.match(ip);
            }, 'Invalid IP address');

            $('#form1').validate({
                rules: {
                    ip: {
                        required: true,
                        IP4Checker: true
                    }
                }
            });

The short version:

简短版本：

^(?!0)(?!.*\.$)((1?\d?\d|25[0-5]|2[0-4]\d)(\.|$)){4}$

You can use regular expressions to test if an IP is valid:

您可以使用正则表达式来测试 IP 是否有效：

"127.0.0.1".match(/^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$/);

This should work for IP address

这应该适用于 IP 地址

$.validator.addMethod('IP4Checker', function(value) {

    var ip="^([01]?\d\d?|2[0-4]\d|25[0-5])\." +
    "([01]?\d\d?|2[0-4]\d|25[0-5])\." +
    "([01]?\d\d?|2[0-4]\d|25[0-5])\." +
    "([01]?\d\d?|2[0-4]\d|25[0-5])$";
        return value.match(ip);
    }, 'Invalid IP address');

    $('#remoteForm').validate({
        rules: {
            ipAddr: {
                required: true,
                IP4Checker: true
            }
        }
    });

Hi this is the best Solution and Mask for IP Adress

嗨，这是 IP 地址的最佳解决方案和掩码

$.validator.addMethod('IP4Checker', function(value) {
        var ip = /^(\d|[1-9]\d|1\d\d|2([0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2([0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2([0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2([0-4]\d|5[0-5]))$/; 
        return value.match(ip);
        }, 'Invalid IP address');

    var $validator = $("#addCardForm").validate({
          rules: {
              txtIP: {
              required: true,
              IP4Checker: true
              }

          }
        });

Addition to answer by @RAVI MONE for IP address with subnet mask:

除了@RAVI MONE 对带有子网掩码的 IP 地址的回答：

$.validator.addMethod('IP4Checker', function(value) {
    var ip="^$|([01]?\d\d?|2[0-4]\d|25[0-5])\." +
      "([01]?\d\d?|2[0-4]\d|25[0-5])\." +

    return value.match(ip);
}, 'Invalid IP address.');

回答by VSB

This function returns trueif IP address is in correct format otherwise it returns false:

true如果 IP 地址格式正确，则此函数返回，否则返回false：

function isIpAddressValid(ipAddress) {
    if (ipAddress == null || ipAddress == "")
        return false;
    var ip = '^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}' +
        '(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$';
    if (ipAddress.match(ip) != null)
        return true;
}

I use jQuery Validation Plugin by:

我通过以下方式使用 jQuery 验证插件：

$.validator.addMethod('IP4Checker', function(value) {
        var ip = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";
            return value.match(ip);
}, 'Invalid IP address');

$('#form').validate({
    rules:{
        ip:{
            required: true,
            IP4Checker: true
        }
    }
});

Hope helpful.
