DNSFetch is a free online DNS lookup service for developers, system administrators, email operators, and anyone else who would rather not install a terminal just to read a public record. You get A, AAAA, MX, NS, TXT, CNAME, SOA, CAA, SRV, reverse DNS, plus SPF, DKIM and DMARC checks and simple policy generators.
Why we built it
Plenty of lookup tools exist. Many sit inside heavier network suites, hide behind accounts, or surround a one-line answer with so much chrome that the TTL is the last thing you find. We wanted something we would use ourselves: fast on a phone, honest about caching, and readable enough to send to a colleague who does not speak dig.
How queries run
Lookups happen on the server, not in your browser. Results are cached for five minutes so a refresh loop does not become a traffic loop toward other people’s nameservers. We rate-limit by IP. We do not sell “premium DNS.” We do not rewrite records. We do not build a public database of what people search. Details are in the Privacy Policy.
Content and ads
The guides exist because the same ten questions appear in every outage channel. They are written to be indexed, cited, and useful without a product pitch in every paragraph. The site may show advertising (including Google AdSense) to keep the lights on. Ads are labeled and are not part of DNS answers.
