an alternative to unicast packets (packets sent to one computer) and 
broadcast packets (packets sent to every computer).

IGMP (Internet Group Multicast Protocol) is a network-layer protocol 
used to establish membership in a multicast group. The ZyXEL Device 
supports both IGMP version 1 and version 2. Select Enable to turn on 
IGMP. Otherwise, select Disable.
