Much work has been undertaken in the browser world to produce the so-called "Happy Eyeballs" outcome. This is an outcome where the client will detect if the service is a dual stack service and if so then use a connection process that slightly biases the client in favour of using IPv6 as the transport for the DNS. What evidence is there for a similar mode of behaviour of DNS resolvers? This presentation will report on a large scale measurement experiment that was intended to expose the protocol behaviour of resolvers and determine whether they have any protocol selection bias.
