Abstract

With the Internet transitioning from IPv4 to IPv6, the number of IPv6-specific DNS records (AAAA) increases. Misconfigurations in these records often go unnoticed, as most systems are provided with connectivity over both IPv4 and IPv6, and automatically fall back to IPv4 in case of connection problems. With IPv6-only networks on the rise, such misconfigurations result in servers or services rendered unreachable. Using long-term active DNS measurements over multiple zones, we qualify and quantify these IPv6-specific misconfigurations. Applying pattern matching on AAAA records revealed which configuration mistakes occur most, the distribution of faulty records per DNS operator, and how these numbers evolved over time. We show that more than 97% of invalid records can be categorized into one of our ten defined main configuration mistakes. Furthermore, we show that while the number and ratio of invalid records decreased over the last two years, the number of DNS operators with at least one faulty AAAA record increased. This emphasizes the need for easily applicable checks in DNS management systems, for which we provide recommendations in the conclusions of this work.
