Setting up my own server (migrating off GCP LB) taught me so much about networking. I was especially surprised that providing IPv6 is such a performance boost for low bandwidth phones since they mostly only operate on IPv6 by now and IPv4 needs some sort of special roundtrip.
IPv6 traffic crosses the 50% mark

#22And still, in the year of our lord 2026, GitHub does not support IPv6. https://github.com/orgs/community/discussions/10539
Came here to exactly check on this to see if there are any changes on Github side too

#23It's only a matter of time before laptops get 5G. Macbooks have been rumoured for a while to get cellular modems. [1]
This will probably help adoption. On the one hand it will generate more IPv6 traffic. On the other hand it will expose more developers to IPv6; which will expose them to any lack of support for IPv6 within their own products.

Re: IPv6 traffic crosses the 50% mark
#24It 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…
Nearly all ISPs these days are deploying IPv6 for their mobile networks and core service networks, especially in less developed markets^1. The reason is simple, a cost justification. What doesn't exist is a cost justification for Enterprises to deploy IPv6, and for ISPs to deploy Residential / Corporate Internet IPv6.
IMO with the right market conditions, IPv6 could spread really fast within 6-24 months. For example, most cloud providers are now charging for IPv4 addresses when IPv6 is free. Small changes like that push in the right direction.

Do we know any technical reason for this? Or are we left to think this is somehow a political thing?
Re: IPv6 traffic crosses the 50% mark
#26Nice. But note that the average is still significantly below 50%. It's also a bit concerning that the growth rate seems to be levelling off. It currently looks like a sigmoid curve with a maximum far below 100%.
I wouldn't be so worried about it. It's really hard for something as big as this to really hit 100%. If we hit 80% or thereabouts, we can at least plausibly argue to backwards ISPs that IPv6 is the default and the standard that everyone should reasonably be offering.
Generally: I'm really surprised that Norway is just at 27%. I think I've been with 3 different residential ISPs the last 15 years, and all of them have done IPv6 perfectly well (two nits: I think one required a trivial opt-in, and my current ISP is just giving me /60 which isn't perfect).
Edit: Oops, sorry to my current ISP for shaming them. Some googling told me that one can get a /56 using DHCPv6-PD. I'll try that!
Re: IPv6 traffic crosses the 50% mark
#27This google metric measures adoption in access networks, but at this point I feel more interesting metric is adoption in services.
One such stat is here:
> adoption ranging from 71% among the top 100 to 32% in the long tail
https://commoncrawl.org/blog/ipv6-adoption-across-the-top-10...
Getting full coverage on AWS (/GCP/Azure) and few other key services (GitHub...) would be significant here imho.

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

Re: IPv6 traffic crosses the 50% mark
#29while it looks like its slowing down, I am pretty sure it will speed up once IPv4 get even more expensive, sites start to be hosted on IPv6 only and become inaccessible to some users that dont have IPv4. Thats surely going to put pressure on ISPs
Outside of hobbyist niche uses, sites won't start being hosted IPv6-only. The financialization of IPv4 addresses will simply get worse and be even more pay-to-play than it is now. Amazon raises the price of IPv4 and everyone goes along as a cost of doing business.
My prediction is that sites will be half-IPv6 only; backends will be IPv6 and IPv4 traffic will get proxied to IPv6 by CDNs / edge LBs. I think CloudFront for example supports that scenario, avoiding IPv4 costs (in theory).

#30Every company I have ever worked for in the US didn't use IPv6 and actually blocked it at the FW
Our freaky network admins rolled it out in our global corpo.
Was fun seeing IPv6 running for a few days without problems.
