Dear Jari and Lars,

Thanks for writing this document, it is a good summary.

1) if we use IPv6 as internal identifier, then it will be
longer than 32 bit, then the size of mapping entry will increase a lot.

2) if we don't use IPv6 as intenral identifier, then how it is
related to IPv6 or IPv6 migration. It could be only called "Save IPv4".

3) Why IETF need to standardize assigning unlimited IPv4 address to the UE?
because we want to encourage prolong IPv4 life for ever?

4) for the second deployment model, if we don't assign IPv4 addres to the host,
would that still be called dual stack?

Best regards,

-Hui
