As a byproduct of our web-based Real User Monitoring (RUM) agent, Dyn obtains the IP addresses of individual hosts running web browsers all over the world as well as the IP addresses of the recursive servers queried by those hosts. We have analyzed a rich data set of over 110 million client IP address-to-recursive IP address mappings to research an area of DNS that we believe has not been suffici ... More

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 present ... More

For example, querying an anycasted resolver like with the command "dig @ whoami.akamai.net" will return an address record revealing a unicast initiator address used by the anycast service. This is "one-le ... More
