Therefore, IPv6 transition mechanisms are needed to enable IPv6 hosts to reach IPv4 services and to allow isolated IPv6 hosts and networks to reach each other over IPv4 infrastructure. [ 51 ] According to Silvia Hagen , a dual-stack implementation of the IPv4 and IPv6 on devices is the easiest way to migrate to IPv6. [ 52 ]
IPv6 has been enabled on 15 websites hosted at Tauranga City Council (TCC). Changes to equipment on the council's internal LAN have also been made to enable IPV6. 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.
There is a difference between a "relay router" and a "border router" (also known as a "6to4 border router"). A 6to4 border router is an IPv6 router supporting a 6to4 pseudo-interface. It is normally the border router between an IPv6 site and a wide-area IPv4 network, where the IPv6 site uses 2002:: / 16 co-related to the IPv4 address used later ...
6in4, sometimes referred to as SIT, [a] is an IPv6 transition mechanism for migrating from Internet Protocol version 4 (IPv4) to IPv6. It is a tunneling protocol that encapsulates IPv6 packets on specially configured IPv4 links according to the specifications of RFC 4213. The IP protocol number for 6in4 is 41, per IANA reservation. [1]
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.
Officially, this mechanism was created for Microsoft Windows XP and onwards PCs to provide IPv6 connectivity to IPv4 clients by connecting to ipv6.microsoft.com and works in conjunction with IP Helper service and Teredo Tunneling Adapter Interface driver. The service also opens a UPNP port on the router for relaying.
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]
A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [2] (routable only within the scope of private networks, but not the global IPv6 Internet).
