I think a mechanism similar to IEEE MAC addresses would be good: organizations can buy a block for a price that's large enough to cover the costs of maintaining the IANA registry and also high enough to make sure people aren't going to buy unreasonable quantities ($/eu 1000 - 5000 or so for a block of a million /48s seems about right) and then the block holders can then redistribute the individual ULA prefixes in any way they see fit. Presumably, end-users would buy their prefixes from distributors that have a good system for enforcing uniqueness in place, but this can be traded off against other needs. _______________________________________________ This message sent to you through the ARIN Public Policy Mailing List (PPML at arin.net).
