DNS Lookup
Look up DNS records (A, AAAA, MX, TXT, CNAME, NS, SOA, CAA) for any domain via DNS-over-HTTPS.
Queries are resolved via Cloudflare DNS-over-HTTPS (1.1.1.1). The domain you look up is sent to Cloudflare.
About DNS Lookup
Query live DNS records for any domain — A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA — directly from your browser using Cloudflare DNS-over-HTTPS. See record values and TTLs in a clean table. Useful for verifying DNS changes, debugging email (MX/SPF/DKIM in TXT), and checking nameservers.
All processing happens entirely in your browser using modern web APIs. Nothing is uploaded to our servers — your data stays local and private. Free to use forever.
Common use cases
- Verifying that a DNS change has propagated
- Checking MX and TXT records when debugging email delivery
- Confirming the nameservers (NS) for a domain
- Inspecting CAA records that control which CAs may issue certificates
- Resolving A/AAAA records to find the IP behind a hostname
How it works
The tool sends a DNS-over-HTTPS (DoH) request to Cloudflare's 1.1.1.1 resolver with the application/dns-json accept header. Cloudflare returns the answer records as JSON, which are decoded (numeric record types mapped back to names like A or MX) and displayed with their TTLs. No DNS server software is needed — the lookup happens over standard HTTPS.
