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,
Lars

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?
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.
