CONFIG_LLMNR_RESPONDER

LLMNR responder

Type: bool

Help

This option enables the LLMNR responder support for Zephyr.
It will listen well-known address ff02::1:3 and 224.0.0.252.
Currently this only returns IP address information.
You must set CONFIG_NET_HOSTNAME to some meaningful value and
then LLMNR will start to respond to <hostname> LLMNR queries.
Note that LLMNR queries should only contain single-label names
so there should be NO dot (".") in the name (RFC 4795 ch 3).
Current implementation does not support TCP.
See RFC 4795 for more details about LLMNR.

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
