NANOG Meeting Presentation Abstract

DNS Query Sent by Heavy Users and DNS Prefetch Effect
Meeting:	NANOG51
Date / Time:	2011-02-02 10:30am - 11:00am
Room:	Grand
Presenters:	Speakers: Kazumichi Sato, NTT.
Abstract:	DNS queries from users have been increasing. We found that number of heavy users sent large number of queries increased during 2009 and 2010. Moreover, we found that number of heavy users who use Firefox increased. We suspect that DNS prefetch increased number of heavy users. DNS prefetch is function that resolves domain names included in URLs in the browsed WEB page. Google Chrome, Firefox, and Safari implement DnS prefetch.
