  2. IPv6 - Wikipedia

    However, dual-stack also needs to be implemented on all routers between the host and the service for which the DNS server has returned an IPv6 address. Dual-stack clients should be configured to prefer IPv6 only if the network is able to forward IPv6 packets using the IPv6 versions of routing protocols.

  3. IPv6 transition mechanism - Wikipedia

    en.wikipedia.org/wiki/IPv6_transition_mechanism

    ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) is an IPv6 transition mechanism meant to transmit IPv6 packets between dual-stack nodes on top of an IPv4 network. Unlike 6over4 (an older similar protocol using IPv4 multicast), ISATAP uses IPv4 as a virtual nonbroadcast multiple-access network (NBMA) data link layer, so that it does not ...

  4. IPv6 address - Wikipedia

    en.wikipedia.org/wiki/IPv6_address

    In this dual-stack configuration, server applications only need to open a single listening socket to handle connections from clients using IPv6 or IPv4 protocols. IPv6 clients are handled natively by default, and IPv4 clients appear as IPv6 clients at their IPv4-mapped IPv6 address.

  5. IPv6 deployment - Wikipedia

    en.wikipedia.org/wiki/IPv6_deployment

    Some internal networks across the organization have been enabled for IPv6, and dual-stack technology is being used to enable both IPv4 and IPv6 use. A number of internal servers and client devices communicate via IPv6, and a teredo relay and 6to4 relay ensure users using these two transition technologies are well served when accessing IPV6 ...

    The Sage 200 task launch will also fail to run if the IPv6 stack is uninstalled. Skype for Business: Windows All Partial The Skype for Business client supports IPv6 only networks where the IPv4 stack is not bound to a network adapter, however it will crash if the IPv4 stack is uninstalled. Smoothwall SWG, UTM and WAM Linux All No SolarWinds ...

    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]

  8. ISATAP - Wikipedia

    en.wikipedia.org/wiki/ISATAP

    ISATAP typically builds its Potential Router List (PRL) by consulting the DNS; hence, in the OSI model it is a lower-layer protocol that relies on a higher layer. A circularity is avoided by relying on an IPv4 DNS server, which does not rely on IPv6 routing being established; however, some network specialists claim that these violations lead to insufficient protocol robustness.

  9. 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.
