WebSub-menu: /interface 6to4. 6to4 is a special mechanism that allows IPv6 packets to be transmitted over IPv4 networks without the need of explicitly configured tunnel interfaces. It is especially useful for connecting two or more IPv6 networks over a network that does not have IPv6 support. There are two different ways of 6to4 mechanism. Web6to4 works by relaying traffic between native IPv6 and IPv4 using relay servers which advertise common IPv4 and IPv6 prefixes to networks they are prepared to provide relay services for, but there is no guarantee that all native IPv6 hosts have a working route toward such a relay. Because of this, a 6to4 host is not guaranteed to be reachable ...
