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.

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).

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

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.

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.

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