IPv6 deployment is slow but ongoing, with major Canadian ISPs (notably Bell Canada) lacking in support for its residential customers, and the majority of their business customers (including server packages). According to Google's statistics, Canada reached an IPv6 adoption level of 39.66% as of May 2022.
The Teredo relay is an IPv6 router that mediates between a Teredo server and the native IPv6 network. ... Imperial College London began experimental IPv6 deployment ...
6rd is a mechanism to facilitate IPv6 rapid deployment across IPv4 infrastructures of Internet service providers (ISPs).. The protocol is derived from 6to4, a preexisting mechanism to transfer IPv6 packets over the IPv4 network, with the significant change that it operates entirely within the end-user's ISP network, thus avoiding the major architectural problems inherent in the design of 6to4.
Special relay servers are also in place that allow 6to4 networks to communicate with native IPv6 networks. [1] 6to4 is especially relevant during the initial phases of deployment to full, native IPv6 connectivity, since IPv6 is not required on nodes between the host and the destination.
DHCPv6 can provide host with the addresses of Domain Name System (DNS) servers, but they can also be provided through Neighbor Discovery Protocol, which is the mechanism for stateless autoconfiguration. [1] Many IPv6 routers, such as routers for residential networks, must be configured automatically with no operator intervention.
NAT64 is a mechanism to allow IPv6 hosts to communicate with IPv4 servers. The NAT64 server is the endpoint for at least one IPv4 address and an IPv6 network segment of 32-bits, e.g., 64:ff9b:: / 96. [3] The IPv6 client embeds the IPv4 address with which it wishes to communicate using these bits, and sends its packets to the resulting address.
The payload of an IPv6 packet is typically a datagram or segment of the higher-level transport layer protocol, but may be data for an internet layer (e.g., ICMPv6) or link layer (e.g., OSPF) instead. IPv6 packets are typically transmitted over the link layer (i.e., over Ethernet or Wi-Fi), which encapsulates each packet in a frame.
Though ReactOS itself has no IPv6 support, ReactOS Foundation services are all IPv6 enabled.
