one reason enterprises use 172.16/12 for stuff is because that way,
when their VPNs come up with people's residents, they do not immediately
conflict with the LAN at the home/coffee shop, etc.
And, there is a further consideration: this space only has to be useable
to for CGNs, for ISPs that have new customers that they want to hook up
via IPv4. Most of these ISPs already provide a home gateway (often
integrated with the DSL model or cable modem), and it only has to work
with that brand!
So I favour 172.16/12 or 224/10.
