Domain Health Report
Combines DNS, WHOIS, SSL, security headers and IP of a domain into one report with warnings.
The domain you type is sent to the Nexinon server, which queries five sources in parallel — the same services already used by DNS Lookup, WHOIS, SSL Checker, Security Headers Analyzer and IP Lookup — and discards everything right after. No query is stored; each section of this report links to the matching dedicated tool, where the same execution notice repeats in detail.
Why check five things at once, not one by one
DNS, registration (WHOIS), TLS certificate, security headers and IP information together give the most complete picture of a domain's health — but they usually live in five separate tools, each requiring a new tab and the same domain typed again. This report fires all five queries in parallel (not one after another) and shows each section as soon as it responds, without waiting for the slowest one — the same work, in a fraction of the time it takes to do it by hand.
Why there is no single score
Mixing DNS, registration, certificate and headers into a single score ("85/100") would hide real information: a domain can have flawless security and a certificate about to expire on the very same day — collapsing that into one number would lie by omission about which of the two problems is urgent. That's why each section shows its own status, in the same vocabulary the original tool already uses, and the summary at the top is an honest list of what needs attention — never an average.
What SPF and DMARC do, and why missing them matters
SPF and DMARC are DNS TXT records that tell other mail servers which sources are allowed to send email on behalf of your domain. Without them, anyone can forge an email that appears to come from your domain (phishing/spoofing) — many mail providers already treat domains without this setup as suspicious by default, which can hurt delivery even for legitimate email. SPF lives in a TXT record on the domain itself; DMARC lives in a TXT record on "_dmarc.<domain>" — that's why the report makes two DNS queries, not one.
Frequently asked questions
No — it's faster. All five queries run in parallel, not one after another, and each section appears as soon as its own source responds. Opening five separate tools, one at a time, always takes longer.
Because it depends on the DNS section's result (it needs the domain's first IPv4 address to know what to look up), and once it fires, it queries five sources of its own behind the scenes (registration, routing, cloud, reverse DNS and geolocation) — the same full IP Lookup tool, just triggered automatically.
See "Why there is no single score" above — mixing such different subjects (DNS, registration, certificate, headers) into one average would hide which problem is actually urgent.
The other four keep working normally — each section has its own loading and error state, and one failing never blocks or taints the others. The failed section shows its own notice, with the link to the dedicated tool still available to try again.
No. It gathers public, objective signals (certificate/registration expiry, SPF/DMARC presence, security headers configured) that any diagnostic tool would check first — it does not replace a professional security review, which also looks at code, infrastructure and processes this report never sees.
