M2M Cellular Gateway
3.7 IPv6
The growth of the Internet has created a need for more addresses than are possible with IPv4. IPv6
(Internet Protocol version 6) is a version of the Internet Protocol (IP) intended to succeed IPv4, which is
the protocol currently used to direct almost all Internet traffic. IPv6 also implements additional features
not present in IPv4. It simplifies aspects of address assignment (stateless address auto‐configuration),
network renumbering and router announcements when changing Internet connectivity providers. This
gateway supports various types of IPv6 connection (Static IPv6 / DHCPv6 / PPPoEv6 / 6to4 / 6in4).
Please contact your ISP the type of IPv6 is supported before you proceed with IPv6 setup.
Static IPv6
Static IPv6 does the same function as static IPv4. The static IPv6 provides manual setting of IPv6
address, IPv6 default gateway address, and IPv6 DNS.
In above diagram depicts the IPv6 IP addressing, type in the information provided by your ISP to
setup the IPv6 network.
DHCPv6
DHCP in IPv6 does the same function as DHCP in IPv4. The DHCP server sends IP address, DNS
server addresses and other possible data to the DHCP client to configure automatically. The server also
sends a lease time of the address and time to recontact the server for IPv6 address renewal. The client
has then to resend a request to renew the IPv6 address.
Index skipping is used to reserve slots for new function insertion, when required.
