Query DNS records and WHOIS data with multi-provider support

How it works: This tool queries DNS records via DNS-over-HTTPS from Google (8.8.8.8), Cloudflare (1.1.1.1), or your system's default resolver. Select "All Records" to query A, AAAA, CNAME, MX, NS, TXT, SOA, SRV, CAA, and PTR records in parallel. WHOIS data is fetched from the RDAP protocol (the modern replacement for traditional WHOIS). Results may differ between providers due to caching and propagation delays.

Frequently Asked Questions

A (IPv4 address), AAAA (IPv6 address), MX (mail servers), TXT (text records, SPF, DKIM), CNAME (aliases), NS (nameservers), and SOA (start of authority).

The tool queries Google's public DNS-over-HTTPS service (dns.google/resolve) which provides DNS resolution results in JSON format. This avoids browser CORS restrictions.

DNS changes take time to propagate (up to 48 hours). Google's DNS may cache records for their TTL duration. If you just changed records, check back later.
