I’m hoping to establish stateful WebRTC connections with individual Machines, and I’ve hit a bit of a roadblock. Without UDP over IPv6, I’d have to allocate a dedicated IPv4 address per Machine (i.e. possibly spin up a new app per each Machine), which rapidly becomes expensive at $2/mo for each IP.
Or perhaps there’s a better way to accomplish this?
I’m also looking at Fly.io’s suitability for hosting a DNS service. In my case IPv4 is more of an impediment than a benefit and ideally I’d have a unique IPv6 address per user. Hopefully this is something Fly.io can fulfil at some point in the near future.
