How to configure JFormattedTextField formatter to display IP address?

I am trying to configure JFormattedTextFieldto display a mask for entering an IP address.

I read javadoc and I tried with ###.###.###.###, but in many cases it is not valid.

I found an article for this, they use the Regex value for formatting, but they do not display a mask for entering an IP address.

Could you help me? Thanks for reading
