Answer 1

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
            }
        }
    });

refer this document IP validation

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

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

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

The short version:

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