I don't think anyone sane would create a top-level that's digits,
particularly in the range of 0 to 255.  That probably means that
somebody is going to do it...  ;-/

I think checking for 2 to 4 dotted octets in the range of 0 to 255
would be safest...  Yes, you can probably get away with using the regex
above, but I wouldn't want to.

 Sucking all the marrow out of life doesn't mean choking on the bone.
