Alejandro, I like that. From a teacher's PoV it would probably very illustrative to have this proposed /20 or /24 but _made up from non-contiguous prefixes_. In the end the goal is to provide each 'team' with a dedicated /32, but if the blocks that these /32s come from are quite different, well, it would look a lot like the 'real' Internet. I can't speak from anyone, but if 4 more blocks like 2001:dbX/29 could be obtained, I think we've mostly solved the problem, in a better way than originally envisioned. The problem of operators having to revisit their prefix lists / ingress ACLs remains, though. Just a thought. ~Carlos On Mon, Aug 19, 2013 at 3:52 PM, Alejandro Acosta < alejandroacostaalamo@gmail.com> wrote: > Hi, > That is a good option. > Another posibility is to tale another RIR similar space and to use > something like 2800:db8::/nn > > Thanks, > > > -----Mensaje original----- > De: Fred Baker (fred) > Enviados: 08/19/2013 1:08:24 PM > Asunto: Re: [v6ops] draft-moreiras-v6ops-rfc3849bis-00 > > > On Aug 19, 2013, at 5:34 AM, Gert Doering <gert@space.net> wrote: > > > 2001:db8 came from APNIC, that's why :-) - their delegated file lists > > > > apnic|AU|ipv6|2001:db0::|32|20031112|allocated > > apnic|AU|ipv6|2001:dc0::|32|20030124|assigned > > > > so an extention to /29 would technically be possible, to a /28 won't. > > Hmm.
