[Freedombox-discuss] IPv6 use? and IETF HomeNet

[Lee Fisher]

Has there been any decision on if FreedomBox is to be IPv4-only, or 
IPv6-only, or NAT/dual-net, or perhaps Tor-only?

If IPv6, and if home networks eventually end up as IETF HomeNet plans, 
it might be nice if a FreedomBox would be able to work from such a 
network arch. Esp. if the IPv6 use of Tor can also work within these 
IPv6 guidelines.

More generally, IMO the IETF HomeNet I-D might be useful to FreedomBox 
Design, for some best-practice advice to consider. Eg:

When an ISP does need to restructure, and in doing so renumber its
customer homenets, 'flash' renumbering is likely to be imposed.  This
implies a need for the homenet to be able to handle a sudden
renumbering event which, unlike the process described in [RFC4192],
would be a 'flag day" event, which means that a graceful renumbering
process moving through a state with two active prefixes in use would
not be possible.  While renumbering can be viewed as an extended
version of an initial numbering process, the difference between flash
renumbering and an initial 'cold start' is the need to provide
service continuity.

There may be cases where local law means some ISPs are required to
change IPv6 prefixes (current IPv4 addresses) for privacy reasons for
their customers.  In such cases it may be possible to avoid an
instant 'flash' renumbering and plan a non-flag day renumbering as
per RFC 4192.

The customer may of course also choose to move to a new ISP, and thus
begin using a new prefix.  In such cases the customer should expect a
discontinuity, and not only may the prefix change but potentially
also the prefix length, if the new ISP offers a different default
size prefix.  Regardless, it's desirable that homenet protocols
support rapid renumbering and that operational processes don't add
unnecessary complexity for the renumbering process.  Further, the
introduction of any new homenet protocols should not make any form of
renumbering any more complex than it already is.
