IPv6 has a notion of link-local addresses (see https://www.rfc-editor.org/rfc/rfc4007),
I found https://labs.ripe.net/author/philip_homburg/whats-the-deal-with-ipv6-link-local-addresses/
helpful for further explanation.
Python uses
(host, port, flowinfo, scope_id)
withflowinfo
andscope_id
being optional.The concrete scenario I was running into was receiving a broadcast packet and not being able
to connect to the sender since it was using link-local addresses.
