• check_domain

  Check a domain that is not working: whether the name resolves in public DNS, then the eleven-check audit of its zone, each row ok, warn, fail or skipped with why. DNS only, not HTTP or TLS, and not for one record: dig. Measured from the isitdns edge and its probes, never the cal…

• dig

  Dig one name and type at one board resolver, or at Cloudflare, Google, Quad9 and AdGuard side by side (resolver all): records, flags, rcode, EDE, latency. Not for a whole domain: check_domain. Asked over DoH from the isitdns edge. from moves the question to that region's probe a…
