Dear Ahmed, I would have completely agreed with you five years ago. Problem is, we've managed to run out of time and 6rd is one of the few transition protocols that has a chance of being implemented in many eyeball networks in the next 12-18 months. I don't like 6RD much either (actually I also don't like how IPv6 reserves 64 bits for the host part), but this is address policy and not the protocol police. Address space that is used is not wasted, and if LIRs use it below the thresholds set in IPv6 allocation policy (which, surprise surprise, 6rd is likely to do) at least those LIRs won't be entitled to any followup address space until they've cleaned up.

In reality RIPE will be giving up a finite resource for implementing one particular type of a transition protocol, i.e. 6rd.
Can't the response be go back to your vendor and ask them to implement a different transition protocol that doesn't waste address space ? After all, there are many such protocols out there.

Interesting to see a v6-in-v4 access protocol triggering a significant change in allocation policy.
As 6rd gobbles up 32 bits for the v4 address at the consumers v6 assignment, there is an alternative in RFC 5572 (TSP) that presents v6-in-v4 access on CPEs without such a need. And TSP can be implemented as a software client so LIRs do not need to change the CPEs to roll out IPv6 to end users.
Dear Ahmed,
We are aware of many similar technologies that would fulfill the same or similar goal, but what we are doing here is just listen to complains and requests from the field and try to make deployment of IPv6 (native or as service in this case) as easy as possible with this change of the policy proposal.
Reality usually wins :)
Cheers, Jan

why are we screwing around? let's go straight to a /16 or at least a /20.
it would not be fair to legacy v6 allocations :)
can only expand to /29 without renumbering :S
cheers, Jan
