Good questions, Remco! Thanks, Géza <div class="gmail_quote">On Mon, May 7, 2012 at 7:34 PM, Remco Van Mook <<a href="mailto:Remco.vanMook@eu.equinix.com" target="_blank">Remco.vanMook@eu.equinix.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <all hats off> Alright then, for the sake of argument I'll oppose until I see some convincing numbers. Back in the original last /8 discussion the rationale for choosing a /22 was that it would get us about 16k final allocations, or 1 for every NCC member and room for the membership to double in size. Now, we have a number of new realities: - final /8 applies to all v4 address space when it kicks in, including space that gets returned later; - It also applies to v4 address space that has not been allocated or assigned by RIPE NCC at that date; - An additional 'special case' block was set aside for IXPs. This all impacts, in a positive or negative way, how much future there is in our final /8 policy. I'd like to think that we made a well-considered decision back then, and if we're going to make a fundamental change like this one I'd like to see some numbers in an impact analysis. Based on current distribution, how much space do we anticipate will fall under the final /8 policy, how much of it will be allocated in /22 PA and how much will be allocated in /24 PI? Given the 'one size fits nobody' nature of the final /8 policy, this would be about the number of allocations/assignments done so far, not the size. Personally I'm rather sick and tired of hearing people say 'yes, let's break IPv4 so we all MUST move to IPv6'. If you think this is good policy or even good engineering, please think again. It will make us end up with a broken internet that, surprise, we won't be managing any more. Breaking IPv4 might lead to increased IPv6 adoption, but not on the internet as we know it today. Everybody who wants to connect his organisation to the internet is going to need at least some IPv4 address space for the time being, so why screw it up for new entrants? Finally, I would like to hear how this proposal correlates to the charge for PI space - the good old 2007-01 chestnut. For post-depletion LIRs, the grapes would be quite sour if one could pick up a quarter of the available resources for about one twentieth of the price. Should "Final /8 PIv4" have a separate price tag? Best Remco This email is from Equinix Europe Limited or one of its associated/subsidiary companies.
