devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the 
AMG1302/AMG1202-TSeries 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).

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 (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 (Internet Protocol version 6), is designed to increase IP address space and enhance features. 
The AMG1302/AMG1202-TSeries supports IPv4/IPv6 dual stack and can connect to IPv4 and IPv6 
networks. See (

) for more information about IPv6.

See

You need to know your Internet access settings such as encapsulation and WAN IP address. Get this 
information from your ISP.
