<HTML> <HEAD> <TITLE>Re: [address-policy-wg] IPv6 allocations for 6RD</TITLE> </HEAD> <BODY> "Nothing is so permanent as a temporary government program." -- Dr. Milton Friedman If we decide to hand out /24s to 6RD and we think that’s not a waste of address space (even though nobody has been able to give me an satisfactory answer I’m willing to throw in the towel) make that a permanent allocation, not a temporary one. The pretense that people will actually hand back that prefix is, let’s say, not consistent with current experiences in IPv4. Once it’s out of the bag it’s out of the bag, never to return.

Just for the record, I've reconsidered and now agree with Michael that we should hand out /24 to ISPs who want to run 6RD, to facilitate /56 handouts to end customers. I would want a discussion on this being 6RD exclusive use and a 5 year temporary handout with option for 5 year extension per time until the community deems that 6RD is depreciated and this space should no longer be used for that. Should we reserve a /8 for 6RD use, approximately one per ASN? Should we just say that a certain /8 is for 6RD use and it's not even handled by RIRs but instead handled like GLOP space for multicast, ie that it's just the ASN mapped into this space? Do we need a /6 to handle future 32bit ASN increase in the next 10 years? Perhaps there should be this kind of IPv4-mapped-into-IPv6-per-ASN space available for general use, not being 6RD exclusive? I do think this should be temporary though, with the aim at this being deprecated in 5-10 years. -- Mikael Abrahamsson email: <a href="swmike@swm.pp.se">swmike@swm.pp.se</a> </BLOCKQUOTE> This email is from Equinix Europe Limited or one of its associated/subsidiary companies.
