Why not use someone else’s IPv4 addresses? Really. What is wrong with using
someone else’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 doesn’t mean that enterprises establishing themselves in a IPv4
/
IPv6 world need to follow that model.
