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, Lars [1] https://www.iana.org/assignments/ipv6-unicast-address-assignments/ipv6-unica...

Perhaps something to do with it being ALLOCATED to the NRO (for rev. dns)? https://6to4.nro.net/ Rob

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.
