Just because you were forced to do silly things in IPv4-land there is no reason to keep doing it.

The discussions I have seen have talked about giving out space like /56s to devices on cellular connections, and that
would allow easy sharing of (many) multiple subnets - of the recommended size /64

Lets hope the mobile networks do something like this and phone vendors provide the tools.


NAT is bad, do not use
bridging would be an ugly kludge
