My fibre provider in the UK has been IPv6 for a while, I have a /56.

Unfortunately, they use CGNAT which is a nightmare for anyone who uses the internet.

I pay them £5 per month to lease an IPv4 address rather than sit behind the CGNAT sharing the IP with all of my neighbors.

Most ISPs have just rolled out cg-nat. I doubt the price of v4 space will ever have any meaningful impact on ipv6 adoption if it hasn’t by now.

I just got ipv6 in my area the last week of November
