OK. But if we all nodes do that and if all nodes publish their records on both IPv4 and IPv6, there is going to be a fair amount of duplicate traffic. More on potential fixes later in this message.


Fair amount of what? DNS, OK, but considering all traffic it is probably neglicable. As always: it is a compromise between implementation complexity, already deployed software, new extensions, new bugs and other factors. And hoping that in a not so far future IPv6 only networks exists.
