RE: IPv6 assignments to DNS root servers in the RIPE region

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Gert, I think what Joao was suggesting was that if the nameserver had been in NASA's v6 block, then rapid renumbering would have made it viable to demand the whole block back from NASA when the nameserver was shutdown. While this is nice in theory, I tend to agree with Randy that it is not very likely in reality for a huge organisation like NASA. Regards, Guy

No, NASA should probably not return their IPv4 space. With IPv6 you can do it right, so why not do it right?
oh, i forgot ipv6's rapid renumbering. i also forgot santa claus and the tooth fairy.
Huh? What does this have to do with anything?
This proposal is about NOT changing IPv6 root name server addresses, and NOT about "easy renumbering".

As I read it, it means that the root-server will get its own allocation, and that allocation follows the rootserver around. Sounds surprisingly reasonable to me. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.

Have a TLA by root server is acceptable. We can then have a fixed root.hint and, why not, include it inside the DNS servers (if root servers never change, why specify them in a dynamic configuration file ?). It can be a default config to have out of the box working DNS servers. But it could be a good thing to explicitly forbid the use of these TLA to any other purpose than hosting a root server and its basic network infrastructure. If organization foo has the X root server and use par of X root server's TLA for anything else, it can be a problem the day organization foo stops hosting the service and has to give back the TLA. We can also change the rfc to add, for example that root servers are located in specific, static adresses. -- Xavier Henner Responsable de l'exp�rimentation IPv6 Nerim -- Fournisseur d'acc�s � Internet URL: <http://www.nerim.net/>

Actually, not quite. I don't believe in IPv6 rapid renumbering. If you allow people to put other services in an address block that block will always be out there, no one will be able to reclaim it (then again I once won the lottery, so strange things do happen). Joao

I understood Joao's proposal differently. If I remember correctly, it explicitely says that this "special IPv6 space" MUST NOT be used for anything not related to IPv6 root operation. So if an organization runs a root server, they would have to have two distinct IPv6 prefixes for "root DNS related" and "all our other stuff". If they use the same IPv6 space for both, they will experience pain, but the proposal explicitely says "do not do that". So if the root server goes away, this special prefix goes away, and the "normal" address space is *untouched* - which makes Randy agree with Joao, in a way: if we do it the "old" way, we can't take the IPv6 address away - but that is not what Joao is proposing.
