Motivation: Diminish the disadvantage of translation. Geoff Huston. APNIC Labs. July 2016. What are we looking at:. How “reliable” are IPv6 connections?. How “fast” are IPv6 connections?. Do all TCP connection attempts succeed?. Is V6 slower than V4?. Michaelson. . APNICLabs. September 2012. What are the questions?. What proportion of DNS resolvers are DNSSEC-capable?. What proportion of users are using DNSSEC-. validatingDNS. resolvers?. Where are these users?. APNIC. https://. xkcd.com. /1361/. Why?. Because everything you do on the net starts with a call to the DNS. If we could see your stream of queries in real time we could assemble a detailed profile of you and interests and activities.

All computers run with some kind of internal oscillator (called a ‘clock’). This clock manages the internal state changes at each cycle of the central processing unit. Clock ‘ticks’ are fed to a digital counter. APNIC. . Measuring the Internet via Users. At APNIC we’ve been using online ads to measure the . u. ser’s view of the Internet for some years.
