Validate IP Address format

[Ankita9793]

Hi,

Can someone please help me with IP address validation Regex, maximum length allowed is 30, should not accept special characters including( "/" and "-" ). Should allow '" , " to enter multiple IPs.

Valid IP address formats example 

Single IP --> 10.1.1.10
Multiple IPs --> 10.0.0.10,10.0.0.11,10.0.0.12

Hi Anurag,
Thanks for responding!!

But it is not working as expected, I am trying to achieve it through client script but my client script does not allow ',' in case of multiple IP addresses

Valid IP address formats are as below... 
Single IP --> 10.1.1.10
Multiple IPs --> 10.0.0.10,10.0.0.11,10.0.0.12

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    var ipAddresses = g_form.getValue('enter_ip_addresses')

    var ipRegex = /^(([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])$/;

    if (!ipRegex.test(ipAddresses)) {

        g_form.clearValue('enter_ip_addresses');

        g_form.triggerErrorChangeFieldSet('No spaces or special characters are allowed', 'enter_ip_addresses');

    }

    if (newValue.length > 30) {

        g_form.clearValue('enter_ip_addresses');

        g_form.showFieldMsg('enter_ip_addresses', 'Allowed maximum length is 30 characters', 'error');

    }

}

Try this

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var ipAddresses = g_form.getValue('enter_ip_addresses')
var ipList = ipAddresses.split(',');
    var ipRegex = /^(([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])$/;
 

for (var i = 0; i < ipList.length; i++) {
    var ip = ipList[i];
    if (ipRegEx.test(ip)) {
        gs.info("Valid IP address: " + ip);
    } else {
        gs.warn("Invalid IP address: " + ip); // You can clear field and throw error here if neeed.
    }
}

  
}
