> 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.
