问题
Is there a good IP Mask plugin for JQuery? I've tried Masked Input Plugin but it doesn't IP Addresses with less than 12 digits. Then I've tried meioMask and this doesn't work with less than 12 digits either. Any suggestions?

You can find your answer in this post :

and a demo for you to try

This is an older post however for someone who wants an easy way to manipulate multiple inputs, without using a bulking plugin, or having to worry about documentation or methods, here's a simple class selector method that does it all for you. Its IPv4 only but it sounds like your needs are pretty simple.
//jQuery 1.9+ selector pattern,
//To get working with an older version
//Swap first line to $(".ip").bind('keydown',function(e){
//To get working with jQuery versions support .live
//$(".ip").live('keydown',function(e){
$(document).on('keydown',".ip",function(e){
var code = e.keyCode || e.which;
var sections = $(this).val().split('.');
//Only check last section!
var isInt = ((code >= 48 && code <= 57) || (code >= 96 && code <= 105));
var hasSlash = $(this).val().indexOf("/") == -1;
if(isInt){
if(hasSlash){
if(sections.length < 4){
//We can add another octet
var val = parseInt(sections[sections.length-1]+String.fromCharCode(code));
if(val > 255 || parseInt(sections[sections.length-1]) == 0){
$(this).val($(this).val()+"."+String.fromCharCode(code));
return false;
}
return true;
} else {
//Lets prevent string manipulations, our string is long enough
var val = parseInt(sections[sections.length-1]+String.fromCharCode(code));
if(val > 255 || parseInt(sections[sections.length-1]) == 0){
return false;
}
return true;
}
} else {
var cidr_split = $(this).val().split('/');
var target_val = parseInt(cidr_split[1]+String.fromCharCode(code));
return (target_val < 33 && target_val.toString().length < 3 && parseInt(cidr_split[1]) != 0);
}
} else if(code == 191){
//CIDR Slash
return ($(this).val().indexOf("/") == -1);
} else if(code == 8 || code == 46 || code == 9 || code == 13){
return true;
}
return false
});
To break this down for understanding, you bind the class "ip" in your input, it will handle the rest automatically :D This version supports CIDR notation (eg: 192.168.1.1/16) it only allows valid addresses to be input, to remove CIDR function you can use use the following snippet (not tested)
//jQuery 1.9+ selector pattern,
//To get working with an older version
//Swap first line to $(".ip").bind('keydown',function(e){
//To get working with jQuery versions support .live
//$(".ip").live('keydown',function(e){
$(document).on('keydown',".ip",function(e){
var code = e.keyCode || e.which;
var sections = $(this).val().split('.');
//Only check last section!
var isInt = ((code >= 48 && code <= 57) || (code >= 96 && code <= 105));
if(isInt){
if(sections.length < 4){
//We can add another octet
var val = parseInt(sections[sections.length-1]+String.fromCharCode(code));
if(val > 255 || parseInt(sections[sections.length-1]) == 0){
$(this).val($(this).val()+"."+String.fromCharCode(code));
return false;
}
return true;
} else {
//Lets prevent string manipulations, our string is long enough
var val = parseInt(sections[sections.length-1]+String.fromCharCode(code));
if(val > 255 || parseInt(sections[sections.length-1]) == 0){
return false;
}
return true;
}
} else if(code == 8 || code == 46 || code == 9 || code == 13){
return true;
}
return false
});
I am providing the code here for two purposes 1) This is something i believe needs to be addressed, 2) i hope to contribute to the world
The snippet is not designed to be pulled apart, nor support IPv6, if you need IPv6 Support please see https://code.google.com/p/jquery-input-ip-address-control/ that anyulled suggested.
But aside from the complex syntax, it breaks the octets apart, and only checks the "active" octet, it supports any VALID address (0.0.0.0, 0.0.0.0/0, ect) so use wisely it does not do any fancy checking other than preventing invalid input. If you're looking for a checker, please see Santiago Elvira Ramirez's post about the IP Address validator.

You could try using this plugin https://code.google.com/p/jquery-input-ip-address-control/

The working examples from the Masked Input Plugin -
http://digitalbush.com/projects/masked-input-plugin/
Are less than 12 characters:
jQuery(function($){
$("#date").mask("99/99/9999");
$("#phone").mask("(999) 999-9999");
$("#tin").mask("99-9999999");
$("#ssn").mask("999-99-9999");
});
They have working examples which are running perfectly?
What is exatly is your issue and can you post anymore in depth information?
jQuery(function($){
$("#MyElementID").mask("10.0.0.0"); //Does this not work?
});
Are you trying to counter for 1-3 digits in each field?
eg to be able to.
$("#MyElementID").mask("1.0.0.0"); //this
$("#MyElementID").mask("10.10.10.10"); //or this
$("#MyElementID").mask("100.100.100.100"); //or this
If you be more descriptive you can get help..
If you are after that you can try something simpler by watermarking the input box rather than enforcing a mask, so you can vary the numbers that can be entered. See Jquery-Watermark - http://code.google.com/p/jquery-watermark/

i found this and you don´t need to install plugins
function fnValidateIPAddress(ipaddr) {
//Remember, this function will validate only Class C IP.
//change to other IP Classes as you need
ipaddr = ipaddr.replace( /\s/g, "") //remove spaces for checking
var re = /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/; //regex. check for digits and in
//all 4 quadrants of the IP
if (re.test(ipaddr)) {
//split into units with dots "."
var parts = ipaddr.split(".");
//if the first unit/quadrant of the IP is zero
if (parseInt(parseFloat(parts[0])) == 0) {
return false;
}
//if the fourth unit/quadrant of the IP is zero
if (parseInt(parseFloat(parts[3])) == 0) {
return false;
}
//if any part is greater than 255
for (var i=0; i<parts.length; i++) {
if (parseInt(parseFloat(parts[i])) > 255){
return false;
}
}
return true;
} else {
return false;
}
}
