[6bone] 6bone phaseout countdown notification - 1 months until phaseout

[Robert Fink]

6bone Operators & Users,

Per RFC 3701, "6bone (IPv6 Testing Address Allocation) Phaseout ", 3FFE
prefixes only remain valid until June 6, 2006.

After June 6, 2006 no 6bone 3FFE prefixes, of any size/length, are to
be used on the Internet in any form.

Note that on June 6, 2006 3FFE prefixes do not actively need to be
returned to the 6bone registry; 3FFE prefixes will simply be invalid
after that date and assumed to be totally under the control of the
IANA.

Network operators may filter 3FFE prefixes on their borders to ensure
these prefixes are not misused.

Because of this, it is highly recommend that all 6Bone participants
take early measures to find alternative IPv6 services, instead of
waiting until the last minute, in order to avoid service disruption.

Please take appropriate action now.


Regards,

Bob Fink
