Public bug reported:
There is a combination of randomly filling in zeros and interpreting
leading zeros as octal.
root@argon:~# ping 010.001.017.001
PING 010.001.017.001 (8.1.15.1) 56(84) bytes of data.

Combination of octal and decimal
If you are going to allow this, there should be a flag to control it. Force
base10, base8, or base16. Perferrably, it would default to base10 only and
require a flag or at least consistent implementation of leading characters for
each octet.
I need a means of ping 010.001.017.001 without having to strip the
leading zeros or converting it to octal.
