networks. It can be static (fixed) or dynamically assigned by the ISP each time the AMG1302-T11C
tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP
encapsulation method).
Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient)
or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of
hosts on the network - not everybody and not just one.
IGMP
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership
in a Multicast group - it is not used to carry user data. There are three versions of IGMP. IGMP
version 2 and 3 are improvements over version 1, but IGMP version 1 is still in wide use.
IPv6
IPv6 (Internet Protocol version 6), is designed to increase IP address space and enhance features.
The AMG1302-T11C supports IPv4/IPv6 dual stack and can connect to IPv4 and IPv6 networks. See
