About newcomers on 5,10 or 20 years... I will not talk about 5 years, but 10 or 20....if in 10-20 years IPv6 is not the main protocol as IPv4 is now, dude, we have a very big problem. We cant know what will happen then.
Indeed. And that's why we have an address policy which tries to arrange for there to be some IPv4 left for the future. Of course everything will be on IPv6 in 10 or 20 years -- aye right as we say in Scotland! -- but even then there might still be a need for teeny amounts of IPv4. Nobody knows for sure. So best keep some in reserve, just in case our grandchildren might come up with a compelling need for them. It's a bit like the Svalbard repository of most of the world's seeds: they're stored in a very safe place just in case there's a disaster and those crop seeds are *really* needed.
But now, year 2014, LIRs with only /22 are having "troubles" managing their network with only 1024 addresses.
Tough. That's all they're going to get. LIRs knew/know that and should have planned accordingly. Throwing away even more IPv4 addresses at these troubles is just not going to help. It might buy a little short-term relief. But it can't make any difference to the eventual outcome. At best it would just push that crunch point back a few weeks or months. And what does the LIR do then, try to get yet another tweak to address policy to squeeze out another /24? Or a /28? When would this exercise in rearranging the furniture on the Titanic finally stop?
What Im trying is to help them (and me!) with that additional /22 (or it could start with /24 since there is a proposal to remove the minium allocation of /22) so they will have a breath while IPv6 are fully deployed on the world.
Sorry, I just don't get it. A new or existing LIR can get one final /22 of v4 along with their IPv6 allocation. What could they do with an additional /24 of v4 that couldn't already be done with that /22? Where's the use case or justification? And not just for your network, but for LIRs in general. If there is a sound, compelling case for this, please make it.
A /24 can give you the chance to grow in customers without wasting in expensive equipment for CGNAT, NAT64, etc.. for some time, maybe the time needed by the rest of the world to finish in the IPv6 deployment.
Er, that's a key reason why LIRs are eligible for their final /22. If this is genuinely not enough to deal with the v4-v6 transition, please explain how much would be and why. For bonus marks, show your working. As they say in school/college exams. :-)
Please, sorry about my very bad english, I know some phrases could not have sense. If so, please tell me and I will try to explain in other way so you all can understand what Im trying to say.
Your English is just fine Daniel. And far, far better than my Spanish. Which admittedly isn't saying much: "una cerveza por favor" :-).
