Hello,

i'm done some research about the impact of missing IPv6 support at the FreeBSD ports-tree, which is the list of supported software for FreeBSD.

Python and many libs written in python are supported for FreeBSD, but if you have an IPv6 only server, they are not usable at all. Currently python has the biggest impact on the ports-tree: (https://wiki.freebsd.org/IPv6PortsTODO#TOP_25_hosts_with_missing_IPv6_support)

This is because the server pypi.python.org lacks support for IPv6. There is also no AAAA record in DNS:

$ drill pypi.python.org aaaa
;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 9429
;; flags: qr rd ra ; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 
;; QUESTION SECTION:
;; pypi.python.org.     IN      AAAA

;; ANSWER SECTION:
pypi.python.org.        6983    IN      CNAME   prod.python.map.fastly.net.
prod.python.map.fastly.net.     5       IN      CNAME   prod.python.map.fastlylb.net.

Please add IPv6 support to your server(s). If you need any help/feedback/tests i will gladly help you!

Thank you very much,
Torsten

FYI pypi.python.org is now managed by the Python infra team. See for example https://mail.python.org/mailman/listinfo/infrastructure and https://status.python.org/

This isn't a CPython issue and doesn't really belong on the issue tracker.

To answer the question though, PyPI will support IPv6 as soon as our CDN provider has support for IPv6 and until they do, it will be IPv4 only.

Thanks for your response Donald!

Which one is your CDN and how will contact it about the missing IPv6 support?

Our provider is Fastly, I don't believe contacting them will do any good though. They are working on getting IPv6 support but there is no ETA at the moment.
