Research direction

Start with the linked Let's Encrypt announcement, then trace the repository's certificate issuance flow to find where hostnames are validated and HTTP-01 challenges are configured. Done means a bare IP address can obtain and use a Let's Encrypt certificate through the normal proxy-host workflow, with the relevant behavior covered by the repository's existing tests if applicable.
