How are we not out of IPv4 addresses already? Aren't there a billion phones out there? And probably the same number of PCs and god knows how many servers?

Regardless of how you calculate the %, it's doubled in a few years.
I still would love to know what they were thinking when they added 252.0.0.0/10 to their list.

#14From what I understand the problem with IPv6 isn't technical problems it is with legacy. According to what I know in Africa and Asia they have mostly already been running on IPv6 the problem is just basically a bunch of lazy network admins in NA and the EU that don't want to learn the new tech and organizations that don't want to switch.

There is a lot of NAT going on these days, and a lot of shared addresses. All those devices aren't all online at the same time.
As I see it, IPv6 can't come fast enough. NAT really needs to die a death so people can actually use the internet fully, not only as a client or using hack-y work-arounds.

#16This is 2.5% of the total adress space - not usable, total. It's about the equivalent of 6.25 class A (/8) prefixes. Quite impressive.
Nothing compared to the US federal government. I count 13 /8 blocks for the DoD, and one for the USPS, so 14 in total.

#17I’d be curious how that compares to other cloud providers.
I've heard Google Cloud doesn't even mess with IPv6, which I find astonishing.

Most of those devices only have a private IP address and use NAT to be able to communicate via the Internet.
Only servers that need to be publicly accessed directly like a web server actually need a public IP.

Is that 252.0.0.0 publicly routed? I can't find an official whois entry, so they just took some reserved address space without asking?
It's listed as reserved here: https://www.iana.org/assignments/ipv4-address-space/ipv4-add...
