Loopback is a Boolean property that indicates if Loopback socket options are used on the Binding for the multicast server. Loopback indicates if the local network module can deliver multicast datagram packets that were transmitted from that network module. 

Changing the value of the Loopback property will result in a change to the socket options for the Binding to ensure that it reflects the new property value. 

The default value for the Loopback is DEF_IMP_LOOPBACK, as assigned during initialization of the component.
