This policy is intended to be a global policy and thus has been submitted in each region. I wrote up my thoughts and concerns and posted to them to the ARIN mailing list - but they are relevant to all regions so I thought I would submit them here to help start a conversation about this policy. I don't really have an opinion as to whether the concept is good/worthwhile yet - but I have a lot of concerns about how this would work, what the repercussions could be and whether it is worth it. As written, I'm currently opposed to this policy. Here's a run down of my questions/concerns. It is not clear whether it is mandatory that RIR's proactively recover space, but it sounds as though it is mandatory that recovered space be turned over to IANA. Is this a conflict? Does this create a dis-incentive to recover space? If address space is returned to an RIR, and they have an immediate need for that space, can they assign it? or *must* they wait for the quarterly interval and return it to IANA? IMO, they shouldn't be forced to return it if they have requests within their region that could be met by reassigning the recovered space. Does this have the potential to break/change rDNS delegations? Geo-location stuff? RPKI? What effect would this have on the RIR's db's? How much work would it be on staff and the db's to break up their aggregates in order to return something? What does this do to aggregation? How will preferences to aggregation be made? It sounds like first come, first serve.. gets the most aggregated prefixes. It sounds as though you can't return space after phase1, is this correct? Intentional? Whatever space starts in the queue by definition could be depleted in 1 year, if each RIR makes a request each 6 months. Is it worth it to extend the "free pool" for one year? Especially if there is no incentive/proactive process to recover space? If RIR's can reassign returned space until the quarterly interval, there may be little if anything to return to IANA. I think this policy doesn't really do anything to extend the free pool or soften the blow of depletion. I imagine there would be the least amount of address space in the queue the first year when it is most needed. If a mechanism to return space after phase 1 existed - the amount of space to delegate could go up - but probably wouldn't for several years, until IPv6 adoption took hold. --Heather On Thu, Feb 19, 2009 at 10:12 AM, Filiz Yilmaz <filiz@ripe.net> wrote:
