Frequently Asked Questions

What is RDAP?

RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It provides structured JSON responses, supports internationalization, and offers better security and privacy controls.

Why use RDAP instead of WHOIS?

RDAP provides standardized, machine-readable JSON responses, supports HTTPS encryption, handles international domain names better, and is the ICANN-mandated replacement for WHOIS.

What TLDs are supported?

Most major TLDs including .com, .net, .org, .io, .dev, .app, .co, .me, and many country-code TLDs. Support depends on the registry providing an RDAP endpoint.
