IP6.ARPA lookups aren't working. Adobe.com doesn't have record so it correctly returns a DNS64 mapped record. However when you attempt to do a IP6.ARPA lookup on that address it does not follow the synthesised CNAME record as you would expect from a recursive DNS64 server. Mark ; <<>

DNS64 is a bad solution. It breaks DNSSEC. The proported benefits of DNS64 over other ways of providing IPv4 over IPv6 don't actually exist. DS-Lite or one of the MAP encapsulation will actually be better in the long run. I say this as someone who has written a DNS64 implementation. Mark In

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

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. On Fri, Aug 15, 2014 at 2:33 PM, Rubens Kuhl wrote: > > > > On Fri, Aug 15, 2014 at 3:29 PM, Tim Durack wrote: > >> Anyone know o
