NANOG Meeting Presentation Abstract

The Resolvers We Use
Meeting:	NANOG63
Date / Time:	2015-02-02 1:30pm - 1:45pm
Room:	Salon I
Presenters:	Speakers: Geoff Huston, APNIC Geoff Huston is the Chief Scientist at APNIC, the regional Internet registry in the Asia Pacific. He has worked in the Internet forever, starting out in the academic and research networks, then serving time in a telco, and more recently doing researchy stuff. He is currently interested in the apparent contradictions of applying privacy and security to the DNS.
Abstract:	We make many assumptions about the way the DNS works. One of the more critical assumptions is that the end user is located "near" to the DNS resolver they end up using. That way content data networks can provide different answers depending on who DNS resolver queries for the content, for example. But is this the case? This presentation shows the result of looking at the correlation between the end user's location and the DNS resolver's location. For every 1 in 3 users we see that they are sending their queries via a DNS resolver located in a different country. This presentation looks into this situation.
