Out of curiosity, of the 37 websites I visit most often, only 10 have IPv6 accessibility.

All websites have IPv4 available. There are no IPv6 only websites.

I decided to configure my computer LAN for dual stack, IPv4 only and IPv6 only to see what was available.

I wouldnt have thought there would be any ipv6-only webservers as that would severely restrict the audience.

I do have some IPv6 only servers which host websites. The difference here is it goes via Cloudflare which provides an IPv4 address also.

I do have some services I host and use (eg log monitoring), which are only available over IPv6 also.

Depending on use case - it does happen.

I think Ray was saying having a public IPv6 only webserver. Yes you may have private services that are accessible only via IPv6 but because they are webservers vs VPN vs anything else doesn't mean too much.

Find me a single popular public website that runs IPv6 only.

NZHerald should be okay:

Interesting.... I ran DIG too and get a report for NZHerald showing both IPv4 and IPv6 addresses.

Yet Chrome and IPvFoo reports only IPv4.

If I have IPv6 only enabled on my LAN, NZHerald does not load load in Chome.

But (also LAN only IPv6)...

C:\WINDOWS\system32>ping -6 nzherald.co.nz

I have IPv4 and native IPv6. I see a lot of large sites are using IPv6 but it's not universal. They should hurry up though as it's definately the way things need to head. APNIC recently reduced the IPv4 103/8 class-A ration to max /23 per company and we are at our limit. If we want any more we will have to buy it on the secondary market at US$5-6k per /24.

On the other hand, we can pretty much have as much IPv6 as we want and are willing to pay for.
