Abstract

We study attempts to dynamically update DNS records for private (RFC1918) addresses, by analyzing the frequency spectrum of updates observed at an authoritative nameserver for these addresses. Using a discrete autocorrelation algorithm we found that updates series have periods of 60 or 75 minutes, which we identified as default settings of out-of-the-box Microsoft Windows 2000 and XP DNS software.
