UDP broadcast is deprecated in general, because it triggers every network
interface on the LAN regardless of whether it’s interested in that packet. UDP
multicast solves that problem by defining multicast addresses that interfaces
can register interest in, so an interface only triggers when a multicast packet
on that address arrives.
WiFi supports UDP multicast.
