Some of them won't have to renumber at all to collapse into a subset (from what I was told). Some are spaghetti messes. Putting out a policy best practice that says "You really should do this, please" doesn't force multi-million-dollar projects, no. But might prompt returns where no renumbering is required. And can hopefully encourage network revamps going forwards to recover space as they go, if it's not too painful. The alternate method - to just openly commoditize it - will also work, but will incur significant political pushback within the community. I don't know which path is ultimately more productive over long timescales. I think that a best practice asking for handbacks is at least harmless in the nearterm. If we need time to overcome opposition to commoditization on our side of the fence, then that should start now, but we can't plan for overcoming that on a particular schedule. Given that APNIC hits their wall in 6-7 months-ish, I don't know that we can move quickly enough, but someone needs to start and see what happens. -- -george william herbert george.herb...@gmail.com
