IP address input

[beast <beast ldap or id>]

I have a text entry which was require user to type an IP address. 
Ideally it should have this following format:

IP Address:   [     .       .      .     ]

Please note that "." is not user editable. Is it possible?

of course, using 4 text entry is possible but thats ugly :)

IP Address:  [  ] . [   ] . [  ] . [   ]
