The 6bone was an IPv6 testbed to assist in the evolution and deployment of IPv6. It was phased out on the 6th of June 2006 per agreements with the IETF IPv6 community.

No 3FFE prefixes are to be in use after 6 June 2006 as these 6bone testbed prefixes have all been returned to the IANA.

The 6bone is an IPv6 testbed to assist in the evolution and deployment of IPv6, the next generation Internet network layer IP protocol often referred to as IPng (see the "Case for IPv6"). These pages provide overview and operational information about the 6bone, and tell you how to join the 6bone. The 6bone operates under the IPv6 Testing Address Allocation of Experimental RFC 2471, allocated by the ngtrans effort of the IETF.  See the NGtrans working group pages for info on this effort.
