Built because "raw data"
isn't an answer.
The problem we kept seeing
DNS is foundational. It controls whether your email arrives, whether your website loads, whether your domain can be spoofed, and whether your security measures actually work.
And yet most DNS tools — even the widely-used ones — present raw records and leave you to figure out what they mean.
You get a long table of DNS data. You get a green tick or a red cross. You get a status code. What you don't get is an answer.
Is this a problem or not? Is it urgent? What do I do about it? Those questions remain unanswered.
What we built
DNSSnuff runs 72 automated checks across every layer of DNS that matters — parent zone delegation, nameserver configuration, SOA health, mail server setup, email authentication (SPF, DKIM, DMARC, BIMI), SSL and web presence, DNSSEC chain of trust, and 50+ blacklist lookups.
Then it tells you what the results mean. In plain English. With specific fix instructions. Ordered by severity so you know what to deal with first.
Free, for any domain, in under 5 seconds. No account. No credit card.
What we believe
DNS health should be accessible.
Understanding whether your domain is correctly configured shouldn't require deep expertise, expensive tooling, or hours of research. One report should tell you everything you need to know.
Plain English is not dumbing down.
Translating technical results into actionable verdicts isn't simplification — it's the actual hard work. The raw records are easy to show. Telling you what they mean is the product.
Free tools build trust.
The DNSSnuff report is free because we want everyone to be able to check. If you find value in monitoring, alerting, and white-label reporting, Pro is there. But the core diagnostic tool will always be free.
72 checks. 8 categories. One verdict. Under 5 seconds.
