IANA 6to4 assignment status

Hi,

Is there a reason why the status of 2002::/16 in IANA's IPv6 unicast assignments list [1] is ALLOCATED (with '6to4' as designation and the note field indicating reservation) rather than RESERVED?

Best regards,

Perhaps something to do with it being ALLOCATED to the NRO (for rev. dns)?

It can probably be moved back to 'reserved' once we're *sure* that 6to4
has finally been stamped out, never to return. But I'm sure that *some*
ISP or company out there is still using it as their main strategy for
migrating to IPv6.

I see, thanks for the explanation.

One follow-up question: Why is the designation "6to4" rather than "IANA"? I would have expected the latter, as 2002::/16---similarly to the individual parts of 2001::/23---is listed under IANA's IPv6 Special-Purpose Address Registry.

Thanks in advance,
