> In 2024 it’s estimated that 20 billion devices use the Internet, yet the Internet’s IPv4 routing table only encompasses 3.03 billion addresses … sharing each individual IPv4 address across an average of 7 devices.

…but the graph below that text shows 40% of traffic is IPv6, so the v4 space is only shared across 12e9 devices?

In my experience the big holdouts these days are corporate networks. All my domestic ISPs (cell, home, data centre) provide IPv6 and most devices use it by default. Meanwhile at the office we’re struggling to bring up a new internal service because our v4 IPAM is a legacy mess where the most you can calve off is a “class A” /27.

FWIW, domestic ISPs in the UK are lagging on IPv6; I'm with Vrigin Media and, afaict, there is no immediate plan to deploy it either.

Virgin neé ntl: has always been complete trash. Are they representative of UK ISPs in general? BT and Sky completed their v6 rollout years ago and they account for over half the market.

When I was in Cambridge Virgin Media used to throttle to dial-up speeds at peak times. Meanwhile, I was still getting advertising leaflets from them through the door trying to sign new people up. Active fraud selling people a service you know you can't provide, and had no timeline to fix.

On the upside, a lot of the UK is getting small fibre companies rolling out 1G symmetric lines all over the place now. I've got that in my new place and it's been great (IPv6, CGNAT IPv4 by default but you can pay £5 for a static IPv4 too).
