> I'd also love if IPv6 only devices had an EASY way to hit IPv4 (ie, xxx:ipv4 in IPv6 address space, with the border device which could be dual stack translating over to IPv4) as a default transition config.
Doesn't NAT64 do exactly that? It translates `64:ff9b::<32 bit IPv4 address>` -> `IPv4`. I get there's stateful/stateless issues and "default" configs (i.e. DNS64), but sounds like the technology is there.
- slownews45 5y agoI think 464XLAT is probably the better solution currently as you can interop with things like websockets etc / SIP? One problem is none of this was default, 464XLAT came out because folks were trying to solve this. That's much different than every router that supports IPv6 auto supports a NAT64 type solution. Other issues are created because of overall protocol differences etc.
