The ISPs do set terms for the customer/provider interface all the time, and rightly so. They can not restrict me from setting up an 802.11 link to my neighbor, only that my neighbor is not allowed to use that for access to the provider's network. In a similar vein, the provider is not in a position to tell customers what address space they can use for purposes that do not interact with the provider interface. They can try, and in a monopoly environment will probably succeed. That does not mean we can tell ISPs to require that people not use any given address space just because the provider is supplying another one. > I also note that site local addresses open up a whole series of > questions about "locality" and scope-range.

Address filtering exists in the network today, and will continue. Since that is done as an expression of local policies, you are correct the whole discussion is really about policy. It is not clear to me what the IETF is in a position to do, other than define the operation of a multifacited DNS. ;) Tony
