Check domain registration, nameserver health, and DNSSEC status. Uses RDAP and DNS-over-HTTPS.
Check domain registration health using RDAP, validate nameserver configuration, and verify DNSSEC status. All lookups run directly from your browser using public RDAP and DNS-over-HTTPS endpoints.
RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It provides structured, machine-readable domain registration data including registrar, creation date, expiry date, and status codes. Unlike WHOIS, RDAP returns JSON and supports internationalization.
Enter your domain in this tool. The registration section shows the expiry date from the RDAP registry. Set a reminder to renew at least 30 days before expiry to avoid accidental lapses.
DNSSEC adds cryptographic signatures to DNS records, preventing attackers from forging DNS responses. You should enable it if your registrar and DNS provider both support it. This tool verifies whether DNSSEC is properly configured.
Status codes like clientTransferProhibited and serverDeleteProhibited are locks that prevent unauthorized changes to your domain. Most active domains should have transfer and delete prohibitions enabled.
RDAP and WHOIS query different servers and may return data at different update intervals. RDAP is the authoritative source for newer TLDs. Some registrars also redact different fields in each protocol.
