Question about JavaScript validators in UI

[Wido den Hollander]

Hi,

While working on the IPv6 for Basic Networking I'm at the stage of the Security 
Groups.

When entering a CIDR in the UI which is not IPv4 (eg ::/0) it will show: 'The 
specified IPv4 CIDR is invalid.'

That's true, so looking in network.js I see this piece of code:

'cidr': {
  edit: true,
  label: 'label.cidr',
  isHidden: true,
  validation: {
    ipv4cidr: true
  }
 },

There is a ipv6cidr validation method as well. How can I modify the JavaScript 
in such a way that either a valid IPv4 OR IPv6 CIDR has to be entered?

My JavaScript skills are rather low.

Thanks!
