Query DNS records for any domain. Look up A, AAAA, MX, TXT, CNAME, NS, SOA, PTR, SRV, and CAA records instantly using Google's public DNS-over-HTTPS resolver.
About DNS Lookup
The Domain Name System (DNS) translates human-readable domain names like example.com into IP addresses that computers use to communicate. DNS records control how traffic is routed, where email is delivered, and how domain ownership is verified.
A records map domains to IPv4 addresses, while AAAA records map to IPv6. MX records specify mail servers, TXT records hold verification data (SPF, DKIM, DMARC), and CNAME records create domain aliases.
This tool queries Google Public DNS (8.8.8.8) via their DNS-over-HTTPS API, providing fast, reliable lookups directly from your browser.
The fully qualified domain name to query — e.g., example.com or subdomain.example.com
DNS record type to query: A (IPv4), AAAA (IPv6), MX (mail), TXT (verification), CNAME (alias), NS (nameservers), SOA, CAA, SRV, PTR
Query sent to Google Public DNS over HTTPS (dns.google) — encrypted and authenticated, unlike traditional plaintext DNS
DNS server returns matching records with TTL (time-to-live), record data, and RCODE (NOERROR, NXDOMAIN, SERVFAIL)
Records displayed with name, type, TTL, and data — multiple records are common for MX, TXT, and NS queries
Spec: RFC 8484 (DNS-over-HTTPS), RFC 1035 (DNS), RFC 7858 (DNS-over-TLS)
