"It's the only free tool that tells you not just what's wrong with your DNS or email setup, but what happens to everything else you depend on when it breaks."
What is DNS SOC? [legend]

DNS SOC runs live DNS, email-authentication, and infrastructure-risk checks against any domain, entirely in your browser — no backend, no account, nothing stored except optional local drift snapshots. Enter a domain above and hit Run diagnostics.

Reading the results: a green dot means the check passed, amber means worth a look, red means a real problem, and blue is informational only. The LIVE tag means a section queries real, current data; SIMULATED means it's a preview of a feature that needs backend infrastructure this browser-only tool can't provide (see each section's own note for specifics).

Records, DNSSEC status, SPF/DMARC/MTA-STS checks below are live — fetched from your browser via public DNS-over-HTTPS resolvers (Cloudflare, Google) in real time. The regional hop trace at the bottom is a simulated preview of the distributed worker-mesh trace from the spec, which needs real probe nodes deployed in each region to be real.

checked against 8 lists: Spamhaus ZEN, SpamCop, Barracuda, SORBS, CBL (abuseat.org), UCEPROTECT Level 1, DroneBL, Blocklist.de — for both the web IP and the mail IP. Note: Spamhaus's free zone blocks queries from public DNS resolvers (which is how this browser-only tool works) and returns "no data" for that zone rather than a real result — this is a known limitation of Spamhaus's own access policy, not a bug in this tool.
