โ Frequently Asked Questions
What is WHOIS lookup?โผ
WHOIS is a query protocol used to look up domain registration information including registrar, registration date, expiration date, and DNS servers. This tool fetches DNS records via Google/Cloudflare DNS-over-HTTPS and WHOIS data via RDAP.
What DNS records can I query?โผ
You can query A records (IPv4), AAAA records (IPv6), MX records (mail servers), NS records (name servers), TXT records (text records including SPF/DKIM), SOA records (Start of Authority), and CNAME records (aliases).
Is this tool free?โผ
Yes, completely free. This tool uses Google and Cloudflare's public DNS-over-HTTPS services for DNS queries and public RDAP endpoints for WHOIS data. No registration required.
Why can't I see some domain info?โผ
Some registrars enable WHOIS privacy protection, hiding registrant information. Certain ccTLD WHOIS data may not be accessible through public APIs. DNS record queries are not affected by this.
How accurate are the results?โผ
DNS record results come from Google and Cloudflare's authoritative DNS servers in real-time. WHOIS registration data may have 24-48 hour caching delays.
