Hi everyone, goedenmiddag Marco! On Fri, Oct 22, 2021 at 01:40:42PM +0200, Marco Davids via NANOG wrote:We currently live in times where is actually fun to go IPv6-only. In my case, as in: running a FreeBSD kernel compiled without the IPv4-stack.Indeed, this is fun experimentation. Shaking the (source code) trees through excercises like these is a valuable way to identify gaps.It turns out that there underlying CDN's with domain names such as ‘l-msedge.net’ and ‘trafficmanager.net’ (Microsoft) or 'fastly.net', that reside on authoritative name servers that *only* have an IPv4 address.As some observant readers noticed (hint: https://ip6.nl/#!deb.debian.org), Fastly is working hard with select customers and friends to support IPv6 for everyone. ** SNIP ** as BGP traffic engineering) might be reluctant to offer IPv6 services "as if they are the same as IPv4". More study is required. Tl;DR - work in progress! :-)
Some of the other CDNs do have IPv6 on the authorities and should work without issues. eg: dig -6 +trace www.akamai.com. - Jared -- Jared Mauch | pgp key available via finger from jared () puck nether net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
