PING 10.1 (10.0.0.1): 56 data bytes
Given that it's how I learned v4 addresses shorten, and that it's
roughly similar to 0-minimization in v6 addresses, I would be
surprised as heck to find any other behavior.
OTOH, I never use it myself, because knowing the answer I still find
it requiring me to stop and think about what it means, because (unlike
the v6 version) there's no visual indication that there are 0's and
where they go. I recently wrote up a C library to parse v4/v6 CIDR
forms, and explicitly chose not to support those shortened v4 forms.
