DoH, DoT and DoQ Servers

This page provides network ranges, IP addresses, and points of presence (PoPs) for well-known DoH, DoQ, and DoT servers. These examples represent only a subset of known server IPs that we track.

Directly routing DoH, DoT, and DoQ requests to external resolvers improves privacy, but at the cost of circumventing local security policies. Increasingly, mobile applications, Smart TVs, and IoT devices are hard-coded to bypass administrative controls, creating significant visibility gaps in the network perimeter.
