Domain & IP Intel
Drop in a domain, URL or IP. We pull WHOIS (RDAP), DNS, email security, geolocation, HTTP & security headers, certificates and well-known files — live, from the edge. Leave it empty to inspect your own connection.
Data sources & privacy
Lookups run on our Cloudflare Worker and query public, keyless services: Cloudflare & Google DNS-over-HTTPS · rdap.org (IANA RDAP bootstrap → registries & RIRs) · ipwho.is & ipapi.is (fallbacks GeoJS, ipinfo.io, ip.sb) for geolocation · SSLMate Cert Spotter (fallback crt.sh) for Certificate Transparency · map tiles © OpenStreetMap contributors. “Your connection” uses Cloudflare's own request metadata. If a provider is down or rate-limits us, that card says so and the rest still work.
Safety: only public hostnames/IPs on ports 80/443 are fetched; private, loopback, link-local and reserved addresses are refused (every redirect is re-checked), requests time out and responses are size-capped. Results may be cached at the edge for a few minutes. We don't store your queries.
