DNS Lookup
Every public record of a domain — A, AAAA, CNAME, MX, TXT, NS, SOA, CAA — queried over encrypted DNS and shown with TTLs an operator can read. The query goes to Cloudflare's resolver when you press the button; the page itself stores nothing and adds nothing.
The phone book, read aloud
DNS is a distributed database with exactly one job: turning names into records. Every check on this page is public information — the same answers any resolver on earth would hand out — which is what makes a lookup tool honest to run: it reveals nothing that was not already published.
The one privacy fact worth stating plainly: the domain you type must reach a resolver, because that is what a lookup is. This page sends it encrypted, to one resolver, only when you ask — and never anywhere else.
Frequently asked questions
Which record type answers which question?
A and AAAA say where the site lives (IPv4 and IPv6). MX says who receives its mail. TXT carries the proofs — SPF, DKIM, domain verification. CNAME says this name is an alias of that one. NS names the servers that hold all of the above, and CAA lists who may issue its TLS certificates.
What does the TTL actually control?
How long resolvers may cache the answer. A 5m TTL means a change propagates within minutes; a 24h TTL means yesterday's value can be served all day. That is why records are dropped to a short TTL before a migration and raised back after.
Why do results here differ from my terminal's dig?
Different resolvers, different caches. Your terminal asks your network's resolver, this page asks Cloudflare's — mid-propagation they legitimately disagree. Comparing the two is itself the standard way to watch a DNS change roll out.
What is DoH and why does this tool use it?
DNS over HTTPS — the query travels encrypted where classic DNS travels as plaintext readable by every network between you and the resolver. It is the same lookup with an envelope, and it is why the browser can make the query at all: plain port-53 DNS is not reachable from a web page.
