Multi-vantage point DNS Diagnostics and Measurement
The ability to measure network and server behaviors from different network vantage points is important for understanding the general health of a network ecosystem. There are various platforms, frameworks, and APIs designed and built to accommodate this need. In this talk we discuss a new DNS looking glass framework designed for low-overhead deployment and great flexibility, and available for use with the DNSViz measurement tool. Recursive and authoritative inspection are both supported, via direct, client-based, or HTTP-proxy-based looking glass perspectives.
