The last time I looked into this (which was a few years ago), ISPs were allocating blocks containing billions of IPv6 addresses to anyone who paid a nominal sum. So that vast address space might not last as long as it would seem...
That sure sounds like a lot. But "billions" is less than a /64. Try "sextillions" (/56) or "septillions" (/48). Of course, when the denominator is "undecillions", it becomes clear that this is actually a non-issue.
I'd even go out of my way and say that undecillion of IP addresses ought to be enough for anybody.

cool, but "read and change your data on all websites" is imho not worth the functionality. that seems ripe for takeover by some scammer.
IPvFoo author here. The problem is that there's no way to obtain the (hostname, ip) stream from Chrome/Firefox without requesting the "all websites" permission. In theory, browser vendors could define a narrowly-scoped permission that only reports (hostname, ip), or roll this functionality into the browser UI, but neither seems likely to happen. I made IPvFoo to promote IPv6 adoption, and wouldn't consider selling it…
To determine ipv4/6, do you need to send that hostname and ip off to somewhere to get a response? or can it be done locally without leaving the machine?

CIDR and the resulting address space fragmentation was the problem that IPv6 was originally meant to solve; allowing splitting into random-sized subnets makes routing more complex and worse. And if you made the routable part of an IPv6 address longer than 64 bits then that makes the routing much more compute-intensive. 64 bits in the local part of the address is sort of overkill, but a 128 bit address isn't really an…
You can still use a shorter hash of the Mac address. Collisions are very unlikely, and a quick ARP packet should detect them if they do happen.

You can do that, sure. But it's more complex and slower.

#95Ha! Beat me to it! For anybody that's curious, the IP-Foo [0] browser extension puts a little 4/6 icon in the address bar to make it clear at a glance which dialect you're speaking for $currentWebPage [0]: https://github.com/pmarks-net/ipvfoo

Just read the source code.

You can determine that by looking at the value.
IPv4: 123.123.123.123
IPv6: 2001:db8::8a2e:370:7334

I actually have the issue where my ISP gives me a single /64 and it makes it difficult to split between multiple LANs.
What do you mean by that? What you do inside your assigned range is completely up to you - you can split that up as you want.
Not if you want SLAAC to work in each LAN. Basically in IPv6 each LAN is supposed to have a /64, that's the real minimum allocation by design. Per the official recommendations, ISPs are supposed to give every individual customer at a minimum a /56.

Can you explain this more? Why are you so tied to ipv4? I recently enabled IPv6 on my home network, and roughly 30-40% of all internet traffic goes through IPv6. Things are noticeably faster, especially connection times to online games on Xbox Live. My only complaint is that my ISP keeps changing the prefix every quarter or so, so my static addresses need to be updated in the firewall and other places. I am looking i…
Why would things be faster over v6?
A possible explanation is the service provider routes IPv4 over their old routers but routes IPv6 over their new routers.

Ah, right. That leaves a custom dhcpv6 pools config for you...
