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.
Charter Communications offers IPv6 access to all of its customers via a freely accessible IPv6 rapid deployment server since at least March 2012. [280] 2012: CenturyLink: CenturyLink offered IPv6 access to all of its customers since at least 2012. [281] 2013: T-Mobile: T-Mobile has made IPv6 its default phone configuration for all new Android 4 ...
Most IPv6 networks use autoconfiguration, which requires the last 64 bits of the address for the host. The first 64 bits are the IPv6 prefix. The first 16 bits of the prefix are always 2002:, the next 32 bits are the IPv4 address, and the last 16 bits of the prefix are available for addressing multiple IPv6 subnets behind the same 6to4 router ...

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 NAT64 server then creates a NAT-mapping between the IPv6 and the IPv4 ...
Happy Eyeballs (also called Fast Fallback) is an algorithm published by the IETF that makes dual-stack applications (those that understand both IPv4 and IPv6) more responsive to users by attempting to connect using both IPv4 and IPv6 at the same time (preferring IPv6), thus minimizing IPv6 brokenness and DNS whitelisting experienced by users that have imperfect IPv6 connections or setups.
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.
Mageia has had full support for IPv6 only and IPv4 + IPv6 since Mageia 7, as well as continuing to support IPv4 only systems. [15] macOS: Mac OS X 10.7 (Lion) Yes Yes Yes [16] Yes [17] Versions 10.7 through 10.10 often prefer IPv4 even when working IPv6 connectivity is available. [18]
