DNS Lookup

Use this DNS lookup page when the issue feels like a domain problem rather than a full service outage. It is useful for checking whether a hostname resolves to the address you expect, confirming that a new record has propagated, or understanding whether mail-routing entries exist before you blame the application itself. The live tool queries Cloudflare DNS-over-HTTPS directly from your browser, which keeps the workflow easy to inspect and avoids a Plain Tools resolver proxy.

That direct model matters for trust. The domain you enter is sent from your browser to Cloudflare because Cloudflare is the resolver providing the answer, but Plain Tools does not sit in the middle or keep a copy of the lookup. The page then groups A, AAAA, and MX results so you can compare address records and mail routes together. If a service still looks broken after the DNS output is normal, the next step is usually a site status or latency check rather than another guess.
