Baldur -

    I am not aware of the RIPE practices with respect to IPv6 end-user
assignments,
    but in the ARIN region, ISPs/LIR's make assignments to end users base=

on similar
    practices that the community adopted for ARIN=E2=80=99s end-user assi=
gnments.
  To my
    knowledge, ARIN does not review these ISP IPv6 end-user assignments
(except
    after the fact and in aggregate if an ISP were to come to ARIN seekin=
g
an additional
    IPv6 block due to utilization of the previous.)

    Differences in policies between the regions is not necessarily any
indication of a
    =E2=80=9Cproblem=E2=80=9D; it can just as easily be an appropriate re=
flection of
different underlying
    circumstances.



The RIPE policy https://www.ripe.net/publications/docs/ripe-641 section
5.4.2 states:

"When a single End Site requires an assignment shorter than a /48, it must
request the assignment with documentation or materials that justify the
request. Requests for multiple or additional prefixes exceeding a /48
assignment for a single End Site will be processed and reviewed (i.e.,
evaluation of justification) at the RIR/NIR level".

For a business user we might go through that process. But my question is
about ordinary residential end users where we want to have as little manual
processing as possible. Therefore we read the above as "do not do that".

We do not entirely disagree with the policy either. I am more looking for a
technical solution, that allows us to deliver a /48 yet still be as
flexible as possible to the users wants and needs.

Baldur

Well you don't know if it is a single end site or two sharing a common
uplink.

You could just configure them both for /49's from the /48 and let them
worry about ip6.arpa sub delegation.  They should be getting a /128
regardless.

That said this really isn't your problem.  It is their problem.
