Use when running PowerDNS dnsdist in docker-compose and wiring dnstap to a local UNIX framestream socket.
Covers: (1) dnsdist-19 Docker image entrypoint gotcha causing "Unable to convert presentation address 'dnsdist'" when you pass a command,
(2) dnsdist newServer() requiring an IP literal (hostnames like recursor:5300 fail),
(3) dnstap CLIENT_RESPONSE address fields: QueryAddress is the downstream client; ResponseAddress is the local bind (dnsdist).
