The Domain Name System (DNS) represents one of the cornerstones of the World Wide Web and plays an indispensable role in its operation. DNS is an extensive distributed database structured to resolve readable domain names for people, companies, and institutions into corresponding and reliable IP addresses. This paper presents PerfResolv, an approach for performance analysis on public DNS resolver servers (e.g., Google, Cloudflare, OpenDNS, Quad9, and ComodoDNS). The analysis was performed with PerfResolv located at geographically distributed points in three different countries: Brazil, Switzerland, and Australia. The results were obtained considering the response time for resolving domain names with different popularity levels to verify if and how geolocation, domain name popularity, week, day, and time affect the performance of DNS resolver servers. The results show considerable fluctuations in the response time of some DNS resolvers, with a variation of up to 40% in response time across different hours of the day. Further, there are differences between the resolution time of popular and unpopular domains, which are also influenced by the geolocation of the measurement monitors. (AU) | |
