You can
always use the link-local address of the interface for LocalAddress. Using
link-local address is preferred and limits the set of addresses Radiator
listens on to the smallest number of possibilities. The default value for
LocalAddress is ::, the IPv6 wildcard address.
On Linux and macOS, you
can configure 'LocalAddress ::'. On Windows, you need to set LocalAddress
to the link-local address of the interface Radiator shares with the DHCPv6
server. Using global address may also work on all operating
systems.
