8.6. Network application commands
8.6.1. mDNS
The mDNS/DNS-SD is a distributed device/service discovery protocol used for resolving
IP addresses and ports on an IP network. In contrast to standard DNS, mDNS protocol is
distributed where each device can join an IP multicast group and advertise its services. Both
IPv4 and IPv6 are supported with addresses 224.0.0.251, FF02::FB and UDP port 5353 are
reserved for mDNS messages. Each module can register to up to five services.
By default, the mDNS service is enabled and the host name and the internal
HTTP server are advertised on enabled interfaces.
The mDNS server is not power optimized. It is recommended to disable mDNS
in battery powered applications
