We developed a binary autocorrelation algorithm and discovered that updates come in in nite series with periods of 60 or 75 minutes. We identify both periods as default settings of out-of-the-box Microsoft Windows 2000 and XP DNS software. Identifying this common property of end-user environments helps to understand users' behavior on the Internet. To our knowledge this is the first study of the global impact of dynamic DNS.
