Re: Dual stack IPv6 for IPv4 depletion

Meanwhile, I'm sitting here on a patio at a cafe on Samos, Greece. And the free wifi gives me native v6 to my tablet and phone without any intervention. Test-ipv6.com tells me that the score is 10/10 and all the google bits just work. So, surely it "just works". I wish we had it this easy in the Netherlands. There, sales still asks, "what for" (Vodafone fiber).

We've had twenty years to implement IPv6 and golly haven't we done a great job? I suppose we could all hope that our kids will be less hopeless than we have been. Still...

No - so why do so many people just keep on and on moaning about how IPv6 doesn't "just work", forgetting that once upon a time IPv4 didn't "just work" either? "Getting there" and "just working" are two things that have to be developed together. One doesn't follow the other, they both become true side by side, or neither happens at all.

How to build an IPv6-only internal network?
by Cryptographrix 09 Jul '15

09 Jul '15

Hypothetically, I want to build an internal network that runs just IPv6 and apply stateless ACLs at redundant external connections. How do users access the current v4 address space?

Re: Dual stack IPv6 for IPv4 depletion

Residential users just buy another router for wifi coverage at the local wall mart. They have no clue about anything internet. That is why isp CPE devices should always perform dhcp-pd on their own to provide a prefix to the downstream devices so those have globally routed ipv6 too. For that to work you need concepts like route aggregation in the form of a /48 for the CPE so it can hand out a /56 to the customer bought CPE.

Doesn't leave that > many allocation blocks for the RIRs to hand out, though. If you really think we have 16.7 Million ISPs on the planet, I think you badly miscounted. In fact, if you think we have 1 million ISPs that have more than 1 million customers, I’d say you’ve badly miscounted something. What am I missing? In terms of ISPs that need to support 16M customers, let’s assume everyone on the planet has 32 ISP subscriptions of some form or another. (work, home, tablet, phone, dongle, whatever… I’m pretty sure 32 is generous). Let’s assume EVERYONE on the planet is connected. That’s 7 Billion * 32 = 224 Billion total customers. Now let’s sparse-allocate 24s at the rate of 4 million customers per /24. 224,000,000,000 / 4,000,000 = 56,000 We need a total of 56,000 /24s to cover the total population. That still leaves us with 16,721,216 /24s. We barely made a dent in the number of /24s. Please explain to me again where the problem is with handing out /48s? > People usually look at IPv6 and focus on the vast numbers of individual > addresses.

Respectfully, I think that the math above shows that you are not correct in this assertion. Owen
