What is this site
Executive summary
This site is a class of online "website intelligence" tools that collect public technical, registration, and historical data about a domain—things like hosting provider, IP address, WHOIS registration, and the technologies a site uses—by querying public registries and scanning the site itself [1] [2] [3]. These services are useful for research, security checks, competitive analysis and takedown requests, but they have clear blind spots: privacy-protected WHOIS entries, cached or inaccurate records, and interpretation errors that require human judgment [4] [5].
1. What the site claims to be and do
The site positions itself as a diagnostic and discovery tool that "knows everything about a website," offering a single place to read domain age and registrar data, see hosting company and datacenter, review DNS and IP history, and list the CMS, analytics and other technologies used on the page [1] [2] [6].
2. Where the data comes from and how it’s compiled
Information typically comes from WHOIS and RDAP registry queries, DNS lookups, IP and ASN databases, public archives like the Wayback Machine, and automated fingerprinting of page assets to infer frameworks and libraries—methods explicitly described by WHOIS services and technology profilers such as who.is, ICANN lookup, and BuiltWith [3] [7] [6].
3. What concrete facts the site can reveal
Practical outputs include registrar name and registration/expiration dates, visible owner contacts when not privacy-hidden, current IP and hosting provider, historic IP changes, server headers and first-archive dates, and a list of detectable front‑ and back‑end technologies such as CMS, JavaScript libraries and analytics scripts [4] [2] [1].
4. Important limits, failure modes and privacy caveats
These tools cannot reliably show private or redacted WHOIS data when registries permit privacy services, and their findings can be stale because WHOIS, DNS propagation and third‑party ranks update at different cadences—domains sometimes remain online long after an organization stops operating and registries can mask true ownership [4] [8]. Automated tech detection also yields false positives or misses custom code; Google’s guidance warns users to seek independent perspectives and background on a source rather than rely solely on automated summaries [5].
5. How to use the site responsibly and verify its claims
Treat outputs as starting points: corroborate ownership or takedown contacts using ICANN/registry lookups and registrar websites, cross‑check hosting and IP information against multiple tools (Netcraft, HostingChecker, BuiltWith) and consult archived snapshots for historical context—independent sources and manual inspection reduce the risk of acting on outdated or incomplete automated reports [1] [8] [6] [7].
6. Bottom line: what this site really is and when to trust it
This site is a convenient aggregator and scanner for public web‑infrastructure signals—powerful for diagnostics, security triage and research—but it is not an authoritative legal or single-source truth; its value depends on the scope of public records, registry policies, and the user’s willingness to validate and acknowledge gaps where data are redacted or ambiguous [3] [5].
