Apart from the documentation Greg shared,
- Remove public IPs from a Fly app, if they’re not required.
-
Listen on
fly-local-6pn
or::
on a port of your choosing (say,1337
servinghttp1.1
) -
Use Fly’s internal DNS to discover private 6pn IPv6 addresses of a particular app in your org by resolving,
global.<appname>.internal
- Talk
http1.1
to one or all of those resolved 6pn IPs on1337
. - Profit?
