@nota @vidister Hmm unless I'm being stupid this should work out to a fraction of (5.77-4)/(6-4)=0.885 of all traffic being v6

props to whoever is achieving adoption numbers that high, nice!

@io @vidister oh yeah, people are always surprised by the high v6 traffic numbers, but it's actually pretty normal!

It's that probability paradox thing where adoption among subscribers is poor and servers are even worse, so the global averages are terrible. But because the highest bandwidth services, the big tech company CDNs, all support v6, if you *do* enable it the far majority of residential traffic will generally be v6 without much work.

@nota @io this creates the weird phenomenon where at night and on weekends/holidays there is a way better IPv6 adoption than during a workday.

@vidister @nota @io we have a dashboard that guesses if we currently have school holidays, based on the fraction of IPv6 traffic on our webservers over the last few days

@9er sounds like that could actually work, my school switched ISPs and havent even enabled IPv6 yet so I wouldn't be surprised if most schools only really use v4

@wilbur We have been ISP for ~3500 schools until a few months ago and yes, that's the sad reality.

@9er @wilbur sounds like "IPv4 based website blocking".

Wilbur

@adorfer @9er it’s not though, all of our schools website blocking is done through DNS (and yes I've tested), the network blocks all port 53 traffic unless it's to a school DNS server (and they break all the time I hate it so much)

@wilbur @adorfer I've made my piece with DNS blocking for schools. Teachers/officials want a way to be legally safe and more important: safe from angry parents. Our service had pretty much 100% uptime over the last few years. We had very very few cases of overblocking. The lists come from a commercial service, so it didn't need any work once it was deployed. Sure, there's usually a way to bypass it, but if someone is smart enough to do that, they could also find other ways to watch porn...

@nota @io @vidister high penetration in mobile networks too (posting from my phone that only has a v6 address, because the network is single stack v6 on the RAN side)

Saxnot

@io @nota @vidister could have calculated 1,77/2 for the same result.

It's not even grouped by service or something. Who knows if >88 % of that traffic is just a single noisy IPv6 service
