MDnsResponderInterface can be accessed by rtc::NetworkManager to generate mDNS hostnames for local IP addresses, so that the addresses of ICE host candidates are obfuscated in gathering whenever an mDNS responder is present. The mDNS responder will handle incoming mDNS queries about the generated mDNS hostnames, e.g. queries received from the AsyncResolverInterface of the remote ICE endpoint.
