Comparison
Whois vs ICANN Lookup
ICANN Lookup
Starting report…
Pick Whois when
- Quick who-owns-this-domain checks
- Security triage of suspicious domains
- Pre-purchase domain due diligence
When Whois is not a fit
- Bulk or automated lookups . use a WHOIS API instead
- Threat-intel teams needing historical registrant data . this is the free teaser
- Anyone expecting owner names or emails . GDPR redaction largely emptied them
