> 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.

Last time I called Virgin media to get from the loyal customer (extra high) rate to something closer to what new customers get they just said no.

I switched to Vodafone which is cheaper and double the speed and got me IPv6. I think it might just be Virgin sitting on a large amount of IPv4 addresses and not wanting to spend any money on supporting v6 when they can just overcharge their loyal customers.

Both BT and Sky are fully IPv6, many altnets are too, it's actually Virgen Media that is the problem in the UK. In the case of Sky they are now running MAP-T and starting the transition to IPv6 only.

Germany, Vodafone. They support it, so I could get v6, but chances are that that'll switch me to CGNAT for v4, so I'm not willing to risk it.

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.

Weird that you have to do an extra step for IPv6. Other ISPs in Germany have enabled it for every customer at some point. Unless your router asks for IPv6 addresses, nothing really changes anyway. So maybe just enable IPv6 on your router and see what happens?

On a side note, there seem to be ways to get out of CGNAT when you got condemned to use it: It is sometimes an annoying source for client VPN instabilities and from what I heard, users can just ask to be switched over from DS-Lite to classic dual stack to improve application compatibility.

No, I have to ask customer service to enable it, my EdgeRouter X supports IPv6.

Anecdata: having switched between Vodafone, Virgin and Sky as my last three ISPs, Virgin was by far the best.

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).

Must be an old contract, all new contracts appear to be CGNAT/native IPv6 across ISPs
