Anybody know of a free custom swing component that represents an IP address. 
Or does anybody know how to format a JTextField to only allow ip addresses. 
So basically I want to keep it in the form 192.168.1.101.

Any suggestions

Thanks

Personally, I would suggest using four fields instead of one, where each 
individual field can contain values ranging from 000 to 255 and perhaps 
typing the third digit could even auto-tab out to the next field.

It would be far easier to write a single JTextField subclass that 
accepts only numeric input and only a max set of digits, etc.  You can 
easily display these in such a way that the dots appear between them on 
other components.  And with a little experimentation, you might even be 
able to set up other restrictions if needed, like not allowing 000 in 
certain octets.

You can attach a specialized document to your textfield. Or use the 
JFormattedTextField with a MaskFormatter.

I know of no way to make JFormattedTextField with a MaskFormatter restrict
to a maximum value.  It would be hard enough to do what I want (for
entering times, restrict the minutes and seconds parts to 00-59), but it
would be much, much harder to restrict a field to 0-255.

I think this covers the subject pretty well:

The 4th way (MVC) is probably the best for this case.
