@trwnh Fedify currently doesn't support binding a custom domain to individual actors—all actors share the server's domain. Honestly, I'm not sure how that would work in practice either; it would need some kind of indirection or delegation mechanism at the HTTP level, and I'm not aware of an established spec for it. Do you have something specific in mind, or perhaps an approach you've been thinking about?

@hongminhee you can use HTTP 3xx redirects but that's not strictly necessary because you can use DNS A/AAAA/CNAME as well (and have the HTTP server respond to those names in conjunction with TLS SNI)

the idea is that multiple server names can be responded to by the same Fedify software instance. in nginx it's doable with the http.server.server_name directive. https://nginx.org/en/docs/http/server_names.html

SNI: https://datatracker.ietf.org/doc/html/rfc6066#section-3

does fedify expect to run behind a reverse proxy? if so, it can route requests.
