IPv6 is an Internet Layer protocol for packet-switched internetworking and provides end-to-end datagram transmission across multiple IP networks, closely adhering to the design principles developed in the previous version of the protocol, Internet Protocol Version 4 (IPv4).
By default, the 6to4 tunneling protocol is enabled in Windows Vista, Windows Server 2008 or later versions when an interface is assigned a public IPv4 address (that is, an IPv4 address that is not in the ranges 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16). 6to4 automatically assigns an IPv6 address to the 6to4 tunneling interface for each such Mar 18, 2020 · If the problems persist, you may need to make additional changes to your configuration for IPv6 to function correctly.

IPv4 is widely deployed and migration to IPv6 would not be easy. So far IPv6 could penetrate IPv4’s address space by less than 1%. The world has celebrated ‘World IPv6 Day’ on June 08, 2011 with a purpose to test IPv6 address over Internet in full. On June 06, 2012 the Internet community officially launched IPv6. Forum discussion: I'm running into some weird issues with IPv6. I'm on the ATT UVERSE Power tier and am using the NVG589 in passthrough mode. I am cascading my RT-N66U (with Merlin firmware
