Global Reachability & Latency
See where a domain resolves and how fast it answers from around the world. Multi-region DNS, IP geolocation, geo-steering / anycast detection, and live latency from worldwide probe nodes.
About
Where is this domain coming from?
A single DNS lookup from your own machine only tells you where a domain points for you. This tool queries the domain through DNS resolvers in different regions and pings it from probe nodes around the world — so you can see whether it answers with the same server everywhere, or steers different regions to different infrastructure.
When every region resolves to the same IP but latency varies by location, the domain is on an anycast network or CDN (like Cloudflare). When regions resolve to different IPs, the domain uses geo-DNS — legitimate for big CDNs, but also a cloaking signal worth investigating on suspicious or lookalike domains.
