Whether Link-Local Multicast Name Resolution (LLMNR) is enabled for the connection.

LLMNR is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link.

The permitted values are: "yes" (2) register hostname and resolving for the connection, "no" (0) disable LLMNR for the interface, "resolve" (1) do not register hostname but allow resolving of LLMNR host names If unspecified, "default" ultimately depends on the DNS plugin (which for systemd-resolved currently means "yes").

This feature requires a plugin which supports LLMNR. Otherwise, the setting has no effect. One such plugin is dns-systemd-resolved.
