Detailed explanation-1: -How UDP works. UDP uses IP to get a datagram from one computer to another. UDP works by gathering data in a UDP packet and adding its own header information to the packet. This data consists of the source and destination ports on which to communicate, the packet length and a checksum.
Detailed explanation-2: -Multicast is a broadcast protocol that doesn’t need a destination IP address. It only needs a port number because it is delivered to all IP’s on the given port. UDP, by contrast, is only delivered to one IP. This is why it needs that destination IP address.
Detailed explanation-3: -UDP does not care about the packets it receives out of order. If UDP receives a sequence of packets out of order, it does not reorder the packets and delivers them to the application out of order.
