            Description

            • Leaving an IGMP group does not guarantee to no longer receive data. Other sockets (either applicative sockets from Socket API, or protocol stack sockets) may still use the same multicast group.
            • In addition, the service will succeed even if the multicast group was not joined upfront.
            • joining and leaving 224.0.0.1 and 224.0.0.2 is not possible.
