     Some Measurements on World IPv6 Day from End-User Perspective
                 draft-keranen-ipv6day-measurements-03

Abstract

   During the World IPv6 Day on June 8th, 2011, several key content
   providers enabled their networks to offer both IPv4 and IPv6
   services.  Hundreds of organizations participated in this effort, and
   in the months and weeks leading up to the event worked hard on
   preparing their networks to support this event.  The event was
   largely unnoticed by the general public, which is a good thing since
   it means that no major problems were detected.  For the Internet,
   however, there was a major change on such a small timescale.  This
   memo discusses measurements that the authors made from the
   perspective of an end-user with good IPv4 and IPv6 connectivity.  Our
   measurements include the number of most popular networks providing
   AAAA records for their service as well as delay and connection
   failure statistics.

1.  Introduction

   Many large content providers participated in World IPv6 Day on June
   8, 2011.  On that day, IPv6 [RFC2460] was enabled by default for 24
   hours on numerous networks and sites that previously supported only
   IPv4.  The aim was to identify any remaining issues with widespread
   IPv6 usage in these networks.  Most of the potential problems
   associated with using IPv6 are, after all, of a practical nature,
   such as: ensuring that the necessary components have IPv6 turned on;
   that configurations are correct; and that any implementation bugs
   have been removed.

   Some content providers have been reluctant to enable IPv6.  The
