DNS Record Resolver & Propagation Inspector
Query DNS records directly over DNS-over-HTTPS (DoH) across Cloudflare, Google, and Quad9 with live latency benchmarking and zero server tracking.
The Architecture of DNS, RFC 8484 (DoH) & Global Resolution
The Domain Name System (DNS) is the distributed hierarchical naming system that maps human-readable hostnames (example.com) to machine-routable IP addresses (93.184.216.34 or 2606:2800:220:1:248:1893:25c8:1946).
DNS Record Types & Functions
- A Record: Maps hostnames to 32-bit IPv4 addresses.
- AAAA Record: Maps hostnames to 128-bit IPv6 addresses.
- CNAME (Canonical Name): Creates an alias pointing one domain name to another.
- MX (Mail Exchange): Directs inbound email traffic to designated mail servers ordered by numerical priority.
- TXT Records: Carries machine-readable data, primarily SPF (Sender Policy Framework), DMARC policies, and domain ownership verification tokens.
- NS (Nameserver): Delegates a DNS zone to authoritative nameservers.
- SOA (Start of Authority): Contains authoritative administrative details, serial numbers, and refresh/retry timers for a DNS zone.
- CAA (Certification Authority Authorization): Restricts which Certificate Authorities (e.g. Let's Encrypt, DigiCert) are authorized to issue TLS certificates for the domain.
DNS-over-HTTPS (DoH) vs Traditional DNS
Legacy DNS operates over unencrypted UDP port 53, leaving requests susceptible to eavesdropping, ISP manipulation, and man-in-the-middle spoofing. DNS-over-HTTPS (RFC 8484) wraps queries in TLS-encrypted HTTP/2 or HTTP/3 streams, guaranteeing confidentiality, integrity, and cryptographic authenticity.
