pathName
    for displaying and editing IP addresses in the standard dotted-decimal
    notation.  The supported options are the same as
    in the case of the mentry::mentry command.type attribute of
    the widget to the value "IPAddr" and returns the name of the
    newly created widget.mentry::ipAddrMentry command defines five new
    keyboard bindings for the entry components of the mentry widget it
    creates:  The Up key increments the entry's value by 1 if
    the latter is less than 255.  Similarly, the Down key
    decrements the entry's value by 1 if the latter is greater than 0. 
    The Prior key increments the entry's value by at most 10 if
    the latter is less than 255.  Similarly, the Next key
    decrements the entry's value by at most 10 if the latter is greater than
    0.  If the entry is empty then all of these keys insert the value
    0 into the entry.  Finally, Control-v
    (Command-v on the Mac) pastes the current contents of the
    clipboad into the mentry, provided that it is a valid IP address.Up and
    Down keys can also be triggered by rolling the mouse
    wheel.  In addition, on Mac OS Classic and Mac OS X/11+ Aqua, the
    actions performed by the Prior and Next keys are
    also triggered by the <Option-MouseWheel>
    event.  The same holds true on all windowing systems if the Tk version
    is 8.7a4 or later, where the Option modifier is bound
    to the Option key on Mac OS X/11+ and to the Alt
    key on Windows and X11.mentry::putIPAddr Commandmentry::putIPAddr – Output an IP address to a mentry
