It could be that they don't want to implement IP bans in IPv6.

Or the most likely more expensive rate limiting (computational wise)

I mean, given how the site performs on average I don't think they've optimized so much that the extra cpu cycles of ANDing with the fixed constant of 2^64-1 and then looking up or hashing a 16 byte integer - whatever they do - rather than a 4 byte one would increase the load significantly. Let's be pessimistic and say it's 20 extra cpu cycles, that's not gonna be much of a problem if their load balancers were made in the past 20 years.

That's extremely common unless on "active" fiber (vs GPON, DOCSIS3, DSL, most fixed wireless, satellite, mobile, etc.) Your wifi isn't symmetrical either.

Those are designed to have static asymmetrical bandwidth though, *dm split gives ISP side more of possible shared bandwidth. Wifi bandwidth is shared and dynamic so client can use all of it.

Is there a reason why adoption has been so abysmally slow? Like surely all the big players have updated their networking equipment by now, and surely every piece of enterprise-grade kit sold in the last 20 years has supported v6. The only arguments I've ever heard against ipv6 that made any sense are that: 1: it's hard to remember addresses, which is mayyyyybe valid for homelab enthusiast types, but for medium scale…

IPv6 is a recursive WTF. It might _look_ like a conservative expansion of IPv4, but it's really not. A lot of operational experience and practices from IPv4 don't apply to IPv6. For example, in IPv4 each host has one local net address, and the gateway uses NAT to let it speak with the Internet. Simple and clean. In IPv6 each host has multiple global addresses. But if your global connection goes down, these addresses…

The reason: Skill issue.

I wonder why Germany has a relative high adoption rate with 77%? They are normally behind when it comes to new technology. Is it because they have more carrier NAT? In Denmark I can get cheap 1 / 1 Gbit/s fiber, but still no ipv6 :(

Carrier-grade NAT for home connections is pretty rare in Germany. I only know of Deutsche Glasfaser - a fairly new ISP that isn't doing too well.

Vodafone cable's cgnat struggles. I went v6 for home so that at least the v6 sites and my own connections avoid the congestion.

Meanwhile: one of the major mobile network in my country announced cisco collab/ipv6 ~5 years ago, but still doesn't provide v6, just v4 CGNAT. Personal web server running dual stack since early 2010s currently sees 18-20% v6 traffic. When split by type, counting only mobile users it reaches 30% at peak. Bot/crawler traffic is ironically 100% v4. Meanwhile: enabled h3 in september last year for the fun of it, instant…

Maybe the best anti-scraper/LLM protection is going IPv6 only. I'd do that on my website, but I'm afraid some clients might not connect.

If GitHub flipped a switch and enabled IPv6 it would instantly break many of their customers who have configured IP based access controls [1]. If the customer's network supports IPv6, the traffic would switch, and if they haven't added their IPv6 addresses to the policy ... boom everything breaks. This is a tricky problem; providers don't have an easy way to correlate addresses or update policies pro-actively. And cu…

Having been messing around personally with getting my own blocks of IP addresses and routing[1] - I've become terrified at the idea of implementing access control based on IP address.

Unless your own organisation in the RR has the IP addresses assigned to you as Provider Independent resources, there just seems to be so many places where 'your' IP address could, albeit most likely accidentally, become not yours any more. And even then, just like domain names, stop renewing the registration and someone else will get them - I was that someone else recently...

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

Perhaps a little tin foil hatty and definitely not the only reason but Microsoft owns Github and also makes a boatload of money off of Azure. Incumbent cloud providers like Azure have a major advantage in terms of having plenty of IPv4 addressing available whereas a new entrant to that market would have to buy or lease that space at a premium. Thus, these companies have an incentive to keep IPv4 a necessity.

IPv4 is going to be a necessity for many many decades no matter what Microsoft do. Even when IPv6 is at 99%, people aren't going to want 1 in every 100 people to not be able to access their site at all. It'll need to be like 99.9% before we start seeing serious IPv6-only services.

As a French national, I am surprised to discover we are topping the charts according to this analysis. Does anybody know why that might be the case? What's the story of IPv6 deployment in France?

Technical literacy, hacker culture, and culture of well-considered infrastructure, have been French characteristics - at least, historically.

Has something changed for the worse?
