RE: [Non-DoD Source] Re: question: are the various IETF web sites IPv6 enabled? If not, why not?

Matt,
I have done some more testing, and have found that when I am connected to the open Internet correctly (not via the VPN used by my office), many of the IETF sites are indeed IPv6 enabled.

However, https://www.irtf.org/  reports “no address” and https://www.rfc-editor.org/ reports “access denied”, so there are still some unexpected results.

Thanks for the feedback.
John

Another possible reason is that your CPE (modem, home router, etc) doesn't properly support IPv6, or isn't configured to do so.

It is taking a long time but we (US and europe) are approaching 50% IPv6.  See Caution-https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-adoption < Caution-https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-adoption >

If you are on net 26/8, you may have other issues as well.

There may be several reasons for that.

Right now, it comes to my mind:
1) Your upstream provider IPv6 connectivity is not able to reach the IETF upstream provider with IPv6.
2) The latency of IPv6 is higher than the IPv4 one.

In those cases, happy eyeballs will prefer IPv4 so you will get IPvfoo extension showing IPv4 as preferred, but if you click, you can still see both the IPv4 and IPv6 addresses as provided by the DNS resolution.

Unfortunately, I've seen way too many ISPs that don't monitor IPv6 with the same degree of quality as IPv4, they rely on customers complains which don't happen because happy eyeballs ...

    Brian,
    Thanks for the quick response. You mention the Firefox "six or not" extension, and that is why I asked the question about IPv6 and IETF websites.

    When I browse the websites you cited, and also Caution-https://tools.ietf.org < Caution-https://tools.ietf.org > , IPvFoo lists several IPv4 addresses, but makes no mention of any IPv6 addresses.

    I can see the IPv6 addresses in DNS, but for some reason IPvFoo reports that the websites respond to web browsers only via IPv4.

    Any theories as to why this is so?

    John

    The "six or not" FireFox extension tells me that the ISOC site invokes a couple of IPv4 services, so needs dual stack. The IETF site is clean in that regard.
