A member of the group only receives the data packets if it is aware of the multicast IP
address and the appropriate application service is available with the specified port number.
IP multicast uses the address range from
224.0.0.0
to
239.255.255.255
(Class D).
Note that certain IP multicast address ranges are reserved for special purposes.
Unicast
The data packets are transferred via point-to-point connection to exact one receiver (client)
in the network including the specified destination IP address and port number.
The receiver only receives the data packets if the appropriate application service is availa-
ble with the specified port number.

TTL
The TTL value (Time To Live) defines the lifetime of an IP packet.
Every router an IP packet passes through reduces the time to live value by one (1). If the
value is zero (0), the IP packet is discarded.
While preventing IP packets from endlessly circulating in the network due to routing errors,
this method stops IP packets from breaking through the limits of the LAN and being sent to
the WAN (TTL = 1).
According to requirements a TTL value from 1 – 255 can be entered. When entering 0
(zero), the default values are used (TTL = 1 for multicast, TTL = 64 for unicast).
