Domain Analyzer
Enter a domain to get its DNS records, email security (SPF/DMARC), registration data, subdomains from certificate transparency logs and its history in the Wayback Machine. Every lookup runs in your browser against public sources.
Domain
Scheme, path and "www." are stripped automatically.
Passive lookups only: the domain's servers are never contacted directly. Queries go to Google DNS, rdap.org, crt.sh / Cert Spotter and archive.org. Data may be cached or out of date.
