Using DNS-first checking (Cloudflare + Google DNS) for fast, reliable results
Verify UNKNOWN/TIMEOUT results with WHOIS after DNS check completes. Slower but more accurate for uncertain domains.
Use cached results for faster checking. Uncheck to force fresh checks and bypass cache.
Note: DNS-first checking is used for speed. WHOIS verification is optional and only runs for uncertain results (UNKNOWN/TIMEOUT).
