CONFIG_MDNS_RESPONDER

mDNS responder

Type: bool

Help

This option enables the mDNS responder support for Zephyr.
It will listen well-known address ff02::fb and 224.0.0.251.
Currently this only returns IP address information.
You must set CONFIG_NET_HOSTNAME to some meaningful value and
then mDNS will start to respond to <hostname>.local mDNS queries.
See RFC 6762 for more details about mDNS.

Direct dependencies

NET_HOSTNAME_ENABLE && NETWORKING

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.

Symbols selected by this symbol

NET_IPV4_IGMP if NET_IPV4
NET_IPV6_MLD if NET_IPV6

Kconfig definition
