224.0.0.0 is not assigned to any group and is used by IP multicast computers.
The address 224.0.0.1 is used for query messages and is assigned to the
permanent group of all IP hosts (including gateways). All hosts must join the
224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is
assigned to the multicast routers group.
The ADSL Router supports both IGMP version 1 (IGMP-v1) and IGMP version 2
(IGMP-v2). At start up, the ADSL Router queries all directly connected networks
to gather group membership. After that, the ADSL Router periodically updates this
information. IP multicasting can be enabled/disabled on the ADSL Router LAN
and/or WAN interfaces in the web configurator (LAN; WAN). Select None to
disable IP multicasting on these interfaces.
