How about just keeping Alexey's code? POSIX doesn't restrict
the IP address format command utilities should accept.  So to
me 127.2.0.0 is a perfectly acceptable interpretation of the
partial address 127.2.

This also has the benefit of not breaking any existing scripts
that already work.  The scripts which are broken will remain
broken which doesn't surprise anyone.
