What is IPv4/IPv6 Dual Stack?
Link-local addresses are not publicly routable. This is the IPv6 equivalent of IPv4's 169.254/16 link-local addresses. The base station will be reachable via IPv6 only from other devices on the data-link networks (wired and wireless Ethernet) directly connected to the base station. It will not act as an IPv6 router or gateway for any other devices. IPv6 - Wikipedia IPv6 is an Internet Layer protocol for packet-switched internetworking and provides end-to-end datagram transmission across multiple IP networks, closely adhering to the design principles developed in the previous version of the protocol, Internet Protocol Version 4 (IPv4).. In addition to offering more addresses, IPv6 also implements features not present in IPv4. IPv6 Modes - Apple | DSLReports Forums Jan 17, 2012

IPSec operates in two different modes: Transport mode (host-to-host) and Tunnel mode (gateway-to-gateway or gateway-to-host). Transport mode: the IPv6 header of the original packet is used, followed by the AH or ESP header, then the payload. Tunnel mode: a new IPv6 header encapsulates the AH or ESP header and the original IP header and payload. Configuring LAN / DMZ IPv6 Interfaces | SonicWall Wire mode and Tap mode for IPv6 need to be configured through the IPv4 interface page. HA interface cannot be configured for IPv6. Only the parent interface of a Switch Port group can be configured as an IPv6 interface, hence all children of a switch port group must be excluded from this list. What exactly does the "IPv6 Passthrough" mode do
Your VPC can operate in dual-stack mode — your resources can communicate over IPv4, or IPv6, or both. IPv4 and IPv6 communication are independent of each other. You cannot disable IPv4 support for your VPC and subnets; this is the default IP addressing system for Amazon VPC and Amazon EC2.
