RE: Private address space in IPv4 and IPv6 [was something irrelevantly titled]
Jeroen, The clash is about: * RIR-space + guaranteed globally unique + CAN be routed on the internet - you will have to do paperwork and pay for it My point of view: RIR-s space is for routing on the Internet. Not for private use! So it MUST be routed on the Internet. And private networks should invent their own rules, personally I will not object that as far as it is not affect my access to public part of the Internet! -----Original Message----- From: Jeroen Massar [mailto:jeroen@unfix.org] Sent: Friday, May 29, 2009 12:37 PM To: Potapov Vladislav Cc: david.freedman@uk.clara.net; nick@inex.ie; frederic@placenet.org; address-policy-wg@ripe.net Subject: Private address space in IPv4 and IPv6 [was something irrelevantly titled] poty@iiat.ru wrote:
Maybe you are right, but it doesn't prove that is IS good in IPv6
world too. I can't understand, why I should think about such private
matters (and indirectly fund this) and count it as arguments in the
RIPE's policy development? If the allocation will never be announced
to the public network called the Internet, then it's not the scope of our thinking!
IPv4: * RFC1918 + just grab - everybody in the world uses it, lots of clashes - not suitable for interconnecting ever to other networks - generally implies a lot of NAT at one point in time * RIR-space + guaranteed globally unique - you will have to do paperwork and pay for it IPv6: * ULA, RFC4193 + nobody to talk to, calculate your own - never to be used anywhere on the Internet - not 100.00000% sure that it is globally unique (also see http://www.sixxs.net/tools/grh/ula/ for a 'registry' which would make it at least "unique" when everybody uses that) - could imply NAT, though that should not be used with IPv6 * RIR-space + guaranteed globally unique + can be routed on the internet - you will have to do paperwork and pay for it You can pick what you want, but heed the warnings.

Bad point of view. You are going to require that people route everything onto the Internet? Not going to happen. There are a lot of assigned blocks which you will never ever see on the Internet. And why would they be, it is their network, thus theirs to route or not, to firewall or not.
And private networks should invent their own rules, personally I will not object that as far as it is not affect my access to public part of the Internet!
You mean a separate registry so that when people are "OH I WANT INTERNETZ" that they simply announce their prefix, which clashes with real prefixes on the Internet !? That will be a lot of fun. The sole reason for having registries in the first place is to make sure these little numbers are globally unique and that they thus don't clash. Ever tried to merge the network of a couple of banks after they where acquired by each other and all where using 192.168.0.0/16 in their internal "totally private" networks? Uniqueness is what is needed there for that to work. With IPv6 one has to option of ULA, for IPv4 though, there is not enough space for such a method, next to that, IPv4 is on the end of its life anyway. If one is going to deploy a network, use IPv6, especially when it is going to be "totally private" anyway, then just use ULA and you are happy. Greets, Jeroen

This is wrong. The Internet Protocol (IP) was not invented only to create the public Internet. It was created so that all networks, that want to interconnect with another network, have an internetworking protocol that does the job. The public Internet is the biggest internetwork but it is not the only one. Globally unique addresses are required so that a network can interconnect with other networks without renumbering. The RIRs are not there to serve the Internet. They are there to serve the users of IP technology which is a bigger group than just the Internet. It is OK for RIPE to provide services that are only needed on the Internet, but it is not nice if RIPE would stop providing services to IP users who are not connected to the Internet. In English, the word "private" has different meanings which cause confusion. In addition we use the word "network" to refer to both networks and internetworks which adds to the confusion. --Michael Dillon
My point of view: RIR-s space is for routing on the Internet.
that is a nice new proposal, but not the way it has been for a few decades. essentially, the lesson has been that, whatever you think now, it is highly likely that it will be connected to the internet eventually. randy
