What is Dns lookup?
DNS Lookup — Free DNS lookup tool — check A, MX, TXT, CNAME and NS records for any domain in seconds via Cloudflare's DNS-over-HTTPS API. No signup needed.
Record data comes live from Cloudflare's public DNS-over-HTTPS JSON API, queried directly from your browser with no backend — the same protocol used by the vendored networktools engine (rezashams991/991-networktools, MIT, src/tools/dns.js): the cloudflare-dns.com/dns-query endpoint, an Accept: application/dns-json header, and the Answer array parsed as name → value pairs. Results reflect Cloudflare's public resolver view, not your local network's resolver. If the API is unreachable you get a clear error, never invented records.

How to use DNS Lookup
- 1Type the domain into the "Domain" box (example.com — no https:// needed, the tool strips it for you).
- 2Pick a record type from the "Record type" dropdown: A, MX, TXT, CNAME or NS.
- 3Run the lookup — the tool queries Cloudflare's public DNS over HTTPS, right from your browser.
- 4Read the record list: each line shows the record name and its published value.
- 5Use the record count to confirm what you expect is live — a count of 0 means no records of that type are published.

Good to know
- Results reflect Cloudflare's public DNS resolver, not your local network's resolver — internal or split-horizon records never appear here.
- Recently changed records may show stale values until DNS caches expire (propagation delay).
- The tool needs internet access to reach Cloudflare's DNS API — if it is down you get a clear error, never partial data.
