On z/OS (and I assume other IBM mainframe operating systems) a
leading zero signifies a leading zero, not a switch to octal.

We include leading zeroes in some IP addresses because it 
simplifies sorting.

It will be "simpler" with IPv6.  The numbers are in hex without need 
for any format indicator.
