Is there a javascript ip address library available in servicenow ?

[Rick25]

Hi,

I'm going to need to some work on the server side with ip addresses. It would be helpful to have a library like:

https://www.npmjs.com/package/ip-address

Is there this kind of thing already available in servicenow?

Regards,

Rick

There's IPAddressValidator script include. It's just calling SncIPAddressV4 class. There's also SncIPRangeV4 class.  Unfortunately, there's no documentation.

Example:

var ipAddressList =['192.168.1.256', '192.168.1.1'];

for (var i=0; i<ipAddressList.length; i++) {
  try {
    var ipAddress = new SncIPAddressV4(ipAddressList[i]);
    gs.info('ip address: ' + ipAddressList[i] + ' is valid.');
  } catch (e) {
    gs.info('ip address:' + ipAddressList[i] + ' is invalid. ' + e.message);
  }
}

Output:

*** Script: ip address:192.168.1.256 is invalid. Address components must be between 0 and 255!
*** Script: ip address: 192.168.1.1 is valid.

I did some work with the OoTB functionality several years ago.  If I can find the scripts I'll share here. 

There are two business rules that reference SncIPAddressV4.  Both provide some insight on SncIPAddressV4 functionality

• Validate IP Range [sys_id: 81804a1ec32312007bf1bea192d3ae61]
• Ensure Unique IP Address Range [sys_id: 488903f6c3d722007bf1bea192d3aef5]

SncIPAddressV4 is also referenced in several script includes.  They also offer some insight on how to use it
