Which entity delivers IPv6 prefixes assignations?
Since IPv6 is still relatively new, the Internet Registrary Board has not yet put forward any addressing plan. However, the 3ffe: prefix is available for IPv6 assignation inside the 6Bone. Thus, in Canada, Dalhousie University and Viagnie Inc have put forward an IPv6 addressing plan based on the prefix 3ffe:b00: /24 for Canadian Gigapops ( http://www.6pop.canet2.net/connections.html ).
