The DNS \"First Mile\"
In this research we measure the round-trip time (RTT) between DNS recursive resolvers and authoritative DNS servers. A significant part of our study analyzes back-end server behaviors for various major public DNS resolver services, such as Google, Cloudflare, Quad9, OpenDNS, and Verisign. We analyze these behaviors from multiple internet vantage points using RIPE Atlas, a global internet measurement platform.
