  2. IPv6 rapid deployment - Wikipedia

    en.wikipedia.org/wiki/IPv6_rapid_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.

  3. IPv6 deployment - Wikipedia

    en.wikipedia.org/wiki/IPv6_deployment

    The deployment of IPv6, the latest version of the Internet Protocol (IP), has been in progress since the mid-2000s. IPv6 was designed as the successor protocol for IPv4 with an expanded addressing space.

  4. IPv6 transition mechanism - Wikipedia

    en.wikipedia.org/wiki/IPv6_transition_mechanism

    6rd was developed by Rémi Després.It is a mechanism to facilitate rapid deployment of the IPv6 service across IPv4 infrastructures of Internet service providers ().It uses stateless address mappings between IPv4 and IPv6 addresses, and transmits IPv6 packets across automatic tunnels that follow the same optimized routes between customer nodes as IPv4 packets.

  5. 6to4 - Wikipedia

    en.wikipedia.org/wiki/6to4

    6to4 is an Internet transition mechanism for migrating from Internet Protocol version 4 (IPv4) to version 6 (IPv6) and a system that allows IPv6 packets to be transmitted over an IPv4 network (generally the IPv4 Internet) without the need to configure explicit tunnels.

  6. Anycast - Wikipedia

    en.wikipedia.org/wiki/Anycast

    In IPv4 to IPv6 transitioning, anycast addressing may be deployed to provide IPv6 compatibility to IPv4 hosts. This method, 6to4 , uses a default gateway with the IP address 192.88.99.1 . [ 15 ] This allows multiple providers to implement 6to4 gateways without hosts having to know each individual provider's gateway addresses. 6to4 has been ...

  8. Happy Eyeballs - Wikipedia

    en.wikipedia.org/wiki/Happy_Eyeballs

    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.

  9. NAT64 - Wikipedia

    en.wikipedia.org/wiki/NAT64

    NAT64 is an IPv6 transition mechanism that facilitates communication between IPv6 and IPv4 hosts by using a form of network address translation (NAT). The NAT64 gateway is a translator between IPv4 and IPv6 protocols, [1] for which function it needs at least one IPv4 address and an IPv6 network segment comprising a 32-bit address space.
