ISPs often fail to do this because there is always someone in the hierarchy who says, "nobody is demanding it."

I worked at a place where they refused to run it _anywhere_ because a couple of people were insistent that it was “insecure”.

... and they were right.

v6 adoption is often an all or nothing, because if you run both stacks, you have to ensure they are consistent. While you can reasonably do it on your home LAN, doing it across an entire infrastructure is the worst.

Now you have to make sure all your subnets, routing, VLANs, firewall rules, etc work exactly the same in two protocols that have very little in common.

It is the equivalent of shipping two programs in different languages and maintaining exact feature parity between both at all times.

Do we know any technical reason for this? Or are we left to think this is somehow a political thing?

IPv6 is very difficult to implement and enforce reliable rate limits on anonymous traffic. This is something we've struggled a lot with - there is no consistent implementation or standard when it comes to assigning of IPv6 addresses. sometimes a machine gets a full /64, other times a whole data center uses a full /64. So then we need to try and build knowledge of what level to block based on which IP range and for so…

... But that's no different from IPv4. Sometimes you have one per user, sometimes there are ~1000 users per IP.

Most of the ipv4 world is now behind CGNAT, one user per ip is simply a wrong assumption.

It has barely hit 50% and it's already plateauing. This adoption rate is ridiculous despite basically all network interfaces supporting it. I thought I would see IPv6 take over in my lifetime as the default for platforms to build on but I can see I was wrong. Enterprise and commercial companies are literally going to hold back internet progress around 60 to 75 years because it's in their best interest to ensure users…

Apple/iOS is probably one of the biggest individual drivers of IPv6 adoption. They've been requiring that iOS apps work on IPv6-only networks for close to 10 years now

The requirement is to support IPv6 only networks with IPv4 transition mechanisms. It does not preclude contacting v4-only servers.

I am aware of at least 2 telecoms, one publicly traded, that have very little to no IPv6 in their core networks and only use IPv6 when they have to.

Personally I think the design of IPv6 offers very little benefit; supposedly the Dept of Defense/Dept of War holds some 175 million IPv4 addresses, with other companies also holding large allocations - that should have been addressed 25-30 years ago as an administrative matter.

IPv6 will never make it. Maybe IPv8 [0], which IPv6 should have actually looked like: > 1.1.1.1.1.1.1.1 [0] https://www.ietf.org/archive/id/draft-thain-ipv8-00.html

Nice idea. Always wondered why IPv6 went so ambitious with the addressing

One of the craziest aspects of IPv6 implementation is the reverse DNS lookups.

IPv6 uses ip6.arpa and segments each little nybble into a subdomain!

https://en.wikipedia.org/wiki/Reverse_DNS_lookup#IPv6_revers...

This means there are always 32 octets to a reverse-IPv6 address, and there are no shortcuts or macros to overcome this! That means if you wish to assign a singular name that maps from a legitimate /64 Network ID, you must populate 64 bits worth of octets in a zone with this data. It is an absurd non-solution. This never should've been allowed to happen, but it will basically mean that ISPs abandon reverse DNS entirely when they migrate to IPv6 implementations.

What? One nine isn’t good enough for you?

Excuse me. Zero nines. Or two nines if you relax your definition of where they are in the number. https://infosec.exchange/@0xabad1dea/116334321751266751

Any idea why it oscillates?

Corporate IT networks have less IPv6 and residential/mobile networks have more IPv6, so on weekdays when people are using Internet at work = more IPv4, weekends when people are using Internet at home = more IPv6. Christmas also has a big bump for the same reason.

Awesome, thanks.

No change in trend during COVID years, interesting.
