Answer 1

refer this document IP validation

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

            $.validator.addMethod('IP4Checker', function(value) {
                return value.match(/^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$/);
            }, 'Invalid IP address');

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

Answer 2

This should work for IP address

$.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
            }
        }
    });

Answer 3

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

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

Answer 4

The short version:

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

Hi this is the best Solution and Mask for IP Adress

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

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

          }
        });
