For a public DNS64 service you also need a public NAT64. I suppose anyone willing to run a Tor exit node might be also willing to run such a service but it would be a traffic source anonymiser and likely would be abused. That said I could see it as a commercial service where only certain sets of IPv6 clients get to use the service with a strict mapping to IPv4 source addresses, logging etc. A ISP which had already set this up for themselves and had enough IPv4 addresses could offer this to IPv6 only ISP's as a service they could buy. Similarly a consortium of ISPs could set this up for their members possibly pooling IPv4 addresses from the members. Someone like HE might like to run such a service to further promote IPv6. This is something transit providers might get into. IPv6 to IPv4 Translation services for IPv6 only clients. The same arguements also work for DS-Lite.

Yeah, sort of agree, except I'm allergic to running services that aren't straight bit shoveling. NAT64 is pushing it, but at least that is just announcing a prefix.

Would be cool if Google added a Public DNS64 service, then I could point the NAT64 prefix at appropriately placed boxes in my network. Why? Other people are better than me at running DNS resolvers :-)No one is better than you at running DNS resolvers with low latency from your network. Even if they can run DNS resolvers with magical capabilities, they will still suffer from transit time. Rubens-- Tim:>
