DNS resolver results
Known resolver networks are often represented by several service addresses. Investigate unexpected providers rather than assuming every additional address is a leak.
The dashboard aggregates reliable client and DNS-leak telemetry to help engineers, support teams, and privacy‑conscious users understand their connection footprint.
Each lookup spawns unique hostnames and records the resolver IP plus provider label. Users immediately see why several Google LLC nodes appear even when pointing clients at 8.8.8.8, and they can spot leaks from unknown networks.

Additional addresses can appear when the browser enables peer connections. Review browser permissions and enterprise policies if the result differs from expectations.
Keep the browser and operating system updated, use encrypted DNS where appropriate, and test again after changing network settings.
Google Public DNS is anycast: the query arrives at 8.8.8.8 but is processed by the closest resolver cluster (172.217.x.x, 172.253.x.x, etc.). The DNS leak widget lists those internal nodes, so several Google LLC IPs mean the traffic still flows through Google. Only unfamiliar networks indicate a potential leak.
Your browser fetches ten random hostnames under our probe domain. Each hostname encodes a unique ID, and our lightweight DNS server logs the resolver IP that requested it. When the widget polls the API we return the list of resolver IPs plus provider metadata sourced from DB-IP, giving you transparency without sending full queries to third parties.
