Description
The selection of which authoritative DNS server to use by a user's DNS resolver of choice greatly determines the user experience when accesing the Internet.
In the past, some studies have looked at the behaviour of a set of implementations describing how they perform authoritative server selection and how they re-evaluate their choices in time [1].
Other studies have leveraged the RIPE Atlas infrastructure to observe DNS resolution of a researcher-owned domain name from various points on the Internet [2].
We extend and complement these studies by using APNIC's distributed ad system to recruit several million end-users throughout the global Internet to observe the resolution selection process as well as its time evolution through a several day period.
