The biggest problem remains cloud and CDN companies with poor to nonexistent IPv6 support. Most ISPs, especially on mobile, have it now or are adding it very soon.

I've wondered whether some might be dragging their feet because they see an advantage in IP address scarcity to sell cloud gateways, CDNs, and other middle box type services. But the most likely explanation remains that not enough customers are asking for it so it's not the highest priority.

I happen to know that Google Cloud started moving on IPv6 seriously only when they lost some big telecom customers to AWS because they didn't have it.

I've never been on a non-mobile connection with IPv6. It's not a thing in Norway.

is the 22+% ipv6 adoption in .no all mobile? (honest question - i don't know)

Except Charter/Spectrum in the US.

Maybe it's because we're in the former Time Warner Cable/Road Runner part of Spectrum's territory, but we've had IPv6 for years now.

I'm in original Charter territory and have v6

Sure, as long as you're ok with having a constantly changing prefix. At least that's how it is for home connections and it nullifies nearly all the benefits of v6.

You don't need a fixed prefix to get most of the benefits of v6.

DNS is a thing.

I can do dynamic DNS on v4 too.

It also complicates firewalls, because now they need to deal with the prefix switching on them and updating their rules to match. As I recall this was only recently added to pfSense.

> IPv6 is available today with an IPv6 capable modem in the majority of Spectrum’s footprint.

Very curious what "majority of Spectrum’s footprint" means in this context.

Telia in Finland refuses to enable IPv6 for mobile. I'm sure there's no lack of providers doing the same.

I'm on Spectrum (via TW acquisition) and have had IPv6 for around a decade, if not longer.

I have it on Spectrum in Ohio. It may vary by market.
