I'm not sure where the /10 is likely to come from - ARIN has offered to donate it, but there is some slush in IANA space (partial networks, etc) that might also work. Personally I'd like to see 240/4 reclassified as experimental private addressing (ie. not Internet unicast), because that allows use in closed environments with a single administrative domain... Whether it ever happens or not depends on how enthusiastic people get about it, I suppose... aj (With a top-posting blackberry) -----Original Message----- From: "Scott Weeks" <surfer(a)mauigateway.com> Sender: nznog-bounces(a)list.waikato.ac.nzDate: Fri, 21 Oct 2011 15:54:12 To: <NZNOG(a)list.waikato.ac.nz> Reply-To: surfer(a)mauigateway.com Subject: Re: [nznog] Bogan Lists? --- aj(a)sneep.net wrote: From: "Alastair Johnson" <aj(a)sneep.net> Not so 10/8 related, but there are still possibilities for prefixes to change status draft-fuller-240space draft-wilson-class-e And of course draft-weil-shared-transition-space-request may also impact with a classification of a prefix from public to "shared transition".

That was of course discussed but the conclusion was that it's hard-coded into many IP stacks as invalid, so it would be pretty much unusable in practice. Brian
