DNS Lookup

Look up DNS records over HTTPS (DoH) or TLS (DoT) with shareable URLs and a public API.

How it works

  • Hostname — the domain to look up (e.g. example.com).
  • Record type — A, AAAA, MX, NS, TXT, etc.
  • Transport — DoH (HTTPS) or DoT (TLS on port 853).
  • Resolver — which provider runs the lookup (Cloudflare, Google, Quad9, …).
