Multicast DNS (mDNS) is used to enable DNS-like name resolution in scenarios in which conventional Unicast DNS name resolution is not possible. It allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link.
The protocol specification is defined by RFC6762.
It is natively supported by Apple OSs, and named Bonjour.
After the MDNS server is initialized by calling the fnet_mdns_init() function, the user application should call the main service-polling function fnet_service_poll() periodically in background.
For the MDNS-server service example, refer to the FNET Shell demo source code.
