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 P-660HWP-Dx supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-
v2
). At start up, the P-660HWP-Dx queries all directly connected networks to gather group 
membership. After that, the P-660HWP-Dx periodically updates this information. IP 
multicasting can be enabled/disabled on the P-660HWP-Dx LAN and/or WAN interfaces in 
the web configurator (LAN; WAN). Select None to disable IP multicasting on these 
interfaces.
6.2.4  Any IP
Traditionally, you must set the IP addresses and the subnet masks of a computer and the P-
660HWP-Dx to be in the same subnet to allow the computer to access the Internet (through the 
P-660HWP-Dx). In cases where your computer is required to use a static IP address in another 
network, you may need to manually configure the network settings of the computer every time 
you want to access the Internet via the P-660HWP-Dx. 
With the Any IP feature and NAT enabled, the P-660HWP-Dx allows a computer to access the 
Internet without changing the network settings (such as IP address and subnet mask) of the 
computer, when the IP addresses of the computer and the P-660HWP-Dx are not in the same 
subnet. Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply 
connect the computer to the P-660HWP-Dx and access the Internet. 
The following figure depicts a scenario where a computer is set to use a static private IP 
address in the corporate environment. In a residential house where a P-660HWP-Dx is 
installed, you can still use the computer to access the Internet without changing the network 
settings, even when the IP addresses of the computer and the P-660HWP-Dx are not in the 
same subnet. 
Figure 54   Any IP Example
The Any IP feature does not apply to a computer using either a dynamic IP address or a static 
IP address that is in the same subnet as the P-660HWP-Dx’s IP address.
