[6bone] report of 6bone planning BOF

Hi Bob,

Just a quick comment on something that was brought up yesterday.

The current draft recommends that IANA not reallocate 3FFE::/16 for two
years from 6/6/06.  On that date, network operators are likely to put
filters on that will block routing for the 6bone prefixes (as may be
considered operationally sound), and there is the danger we end up in
the same position as the IPv4 world is currently experiencing with
69.0.0.0/8 (see the NANOG archives if you're unfamiliar with this
problem).  A note regarding the future global routability of 3FFE::/16
might be a worthwhile addition, do others agree?

Regards,
Rob
