DNS Lookup
Query A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, and SRV records via Cloudflare's DNS-over-HTTPS API.
Tip: TXT often contains SPF; pair with the SPF/DKIM/DMARC parser.
Type reference for completeness: A=1 · NS=2 · CNAME=5 · SOA=6 · PTR=12 · MX=15 · TXT=16 · AAAA=28 · SRV=33 · CAA=257🔒 The browser queries cloudflare-dns.com directly. No data passes through BEAD servers.
How it works
Queries hit https://cloudflare-dns.com/dns-query with the application/dns-jsoncontent type — Cloudflare's CORS-friendly DNS-over-HTTPS endpoint. Results come straight to your browser; this site never sees the names you look up.
The All commonbutton fans out to A, AAAA, MX, TXT, NS, CNAME, SOA, and CAA in parallel — a quick "everything about this domain" snapshot.
