How do I look up a domain with ICANN WHOIS or RDAP?

| ICANN WHOIS | Best for a familiar registration lookup and registrar context. |
|---|---|
| RDAP | Best for structured registry data and machine-readable fields. |
| DNS lookup | Best for current A, AAAA, MX, TXT, NS, and other DNS records. |
Worked example: Example: enter example.com, prepare the RDAP and ICANN links, then compare registrar, registration status, and date fields in the authoritative result.
Recommendation: Start with RDAP for structured data, then cross-check ICANN WHOIS when ownership or registrar details matter.
Limit: Privacy redaction, registry policy, and registrar data can hide contact details or return different fields.
