A UD endpoint can communicate using multicast and to other UD endpoints. A

So the IP world analog would be:
fd = socket(AF_INET,SOCK_DGRAM);
connect(fd,'Some Unicast Address');
setsockopt(fd,IP_MULITCAST_ADD_MEMBERSHIP,'Some Multicast Address');
sendto(fd,...,'Some Multicast Address');
IP multicast senders don't call IP_ADD_MEMBERSHIP, only receivers
