WHOIS lookup (RDAP)
Structured registration data from the registry’s RDAP service—how modern DNS tooling exposes domain status, dates, and policy flags.
What WHOIS / RDAP here means
Registration data (registrar, status flags, sometimes dates and contacts) is published by registries using RDAP over HTTPS, the modern successor to classic port-43 WHOIS. Assistants and SEO tooling increasingly expect structured RDAP JSON rather than plain-text screens.
This tool looks up your domain against the RDAP service listed in IANA’s bootstrap data for your TLD. Coverage and redaction vary: many TLDs hide personal data while still exposing technical and policy fields.
Use it to see registry-reported status, understand which RDAP server answers for a TLD, and cross-check renewal or transfer questions—not as legal proof or a replacement for your registrar’s console.
How this tool works
Short technical summary of what runs on our servers when you click the button.
We download (with caching) the public DNS RDAP bootstrap file, pick the longest matching public suffix, then request JSON from the registry’s RDAP endpoint.
You get the registry’s RDAP object. We summarize common fields in plain language and keep the full JSON available for power users.
Internal-only hostnames are rejected. This is a registration-data lookup, not a port scanner.
