Why not use someone elseâ??s IPv4 addresses?  Really.  What is wrong with using
someone elseâ??s IPv4 addresses if it achieves the need?  As far as I can tell
nothing.

Just because enterprises that established themselves in a  IPv4-only world did
it one way.  It doesnâ??t mean that enterprises establishing themselves in a IPv4 /
IPv6 world need to follow that model.
