Re: IPv6 allocation plan, security, and 6-to-4 conversion

* William Herrin

nat64/nat46 - allows an IPv6-only host to interact in limited ways with IPv4-only hosts. Don't go down this rabbit hole. This will probably be useful in the waning days of IPv4 when folks are dismantling their IPv4 networks but for now the corner cases will drive you nuts. Plan on dual-stacking any network which requires access to IPv4 resources such as the public Internet.

For many folks, that's easier said than done. Think about it: If everyone could just dual-stack their networks, they might as well single-stack them on IPv4 instead; there would be no point whatsoever in transitioning to IPv6 for anyone. Tore
