ULAs are clearly routable over whatever scope people decide to. This was also true of the SiteLocal prefix that ULAs are replacing. The only difference is that ULAs have explicit text to avoid routing ambiguity where SL didn't. I argued against deprecating SL partly on the basis that it had the potential for ambiguity which would be a disincentive for grey-market PI use. I understand and agree with your point about them being a potential problem, but that potential is easily mitigated by providing an economically viable alternative. > > > The current problem is that the RIR membership has self-selected to a > > state where they set policies that ensure the end customer has no > > alternative except to be locked into their provider's address space. > > Everyone acknowledges that the demand for PI space is real while > > simultaneously refusing to seriously deal with it (and the > > re-architecting of fundamental assumptions about the Internet effort of > > multi6, while serious, is not a short term solution). > > > This is absolutely not true.

None of the organizations that are getting long IPv4 allocations will qualify for an IPv6 prefix. There is an implicit concession that it is too late to close the barn door for IPv4, but for IPv6 it is currently locked tight by those that want to maintain control. > > > My to-do list for the next couple of weeks has an item to ask for a BoF > at > > the next IETF on an interim moderately aggregatible PI approach.

Multi-homing is only one reason for PI space, and people get so hung up on that one that they forget that the simple ability to change providers without massive effort is just as important. > > As I see it, IP Addresses are currently used for the following purposes: > > Destination Endpoint Identifier (resolvable by requiring a solid > directory > service) > Source Endpoint Identifier (mostly doesn't matter when this changes) > Source Endpoint Authentication (this is bad and we should be using > something better > that actually identifies the host (or better yet in most > cases, user) > in a meaningful way) > Host authorization (Same issue(s) as previous statement) > Portion of Service authorizatoin decisions (again, same issues as > previous > two) > > In the early days of the ipng working group, there was hope that v6 would > solve these > issues.

The issue is many assumptions have been made at all layers of the system about the alignment of all those characteristics, so just ripping them out doesn't really solve anything more than the routing problem. Even if the multi6 follow-on groups come up with a technical approach that splits the functions, all the rest of the infrastructure will need to adapt and that will take much longer than rolling out IPv6. Making a change that intentionally breaks fundamental assumptions will meet much greater deployment resistance than something that intentionally minimized such changes. Call the intentional minimization a failure if you must, but from my perspective the only real failure will be to let the Internet collapse into something less capable of delivering end user services than X.25 was.
