PUBLIC DNS / REVIEWABLE EVIDENCE

Know what a signal can tell you.

Explore 125 vendor/product names across 159 registry rules. Scanner source 0.5.0, catalog 2026.10.15. Coverage describes observable DNS configuration, not paid customers or active adoption.

Available on npm: vendorprint 0.5.0. Run npx vendorprint@0.5.0 example.com to use this catalog. The dated benchmarks below retain their original scanner versions.

New in 0.5.0

Exact input hostnames and www are queried directly. Scoped hostname hints improve discovery within the 80-attempt budget. Compact results include observation time and scan completeness, so budget limits and DNS errors remain visible alongside findings.

New domain-verification rules cover Smartsheet, Dynatrace, TeamViewer, and Adobe Acrobat Sign. These indicate published domain relationships, not current subscriptions or activity. Read the validation evidence.

Two cohorts. Separate baselines.

Direct product configuration requires a non-wildcard, vendor-specific CNAME or delegated nameserver in a business-product category. General website hosting, email delivery, and mail productivity are excluded from this headline. Category percentages include broader TXT and SPF relationships. Every sourced input stays in the denominator, including invalid inputs and limited responses.

500 company domains from Installmap’s 2026 Fortune 500 cohort; a third-party company/domain mapping, not independent verification of current rank or corporate ownership. All source rows retained regardless of source website-crawl success. New baseline, not comparable to the old Inc. cohort.

These measurements replace the historical August Inc. 5000 figures with a new Fortune 500 domain baseline and a fresh software-cohort scan. They are not a like-for-like improvement claim, precision estimate, or recall estimate. Budget limits, unqueried hostnames, redirects, and proxying can hide signals.

Find a vendor or a DNS pattern.

This catalog lists the versioned CNAME, TXT-verification, SPF, DKIM, and delegated-NS registry. General MX, DNS-provider, and DMARC classifiers are additional coverage outside this count. Confidence is rule-level where recorded; normalized profile confidence and scope remain authoritative. Some older rules still lack recorded source links.

Useful boundaries.

Vanta, SafeBase, and Drata CNAMEs identify trust-center hosting, not certification. Snowflake TXT identifies an organization email-domain relationship, not warehouse workloads. Fireflies and Read AI domain records do not prove meeting activity. Gong Engage tracking does not identify general Gong call recording. No reliable Granola, 6sense, Demandbase, or Engagio customer-detection rule is claimed.
