How this service works
Is the domain's DNS hosted by cloudns? Looks up the NS records (Cloudflare DoH) and matches them against cloudns's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.
Output
Returns a boolean yes/no indicating whether the domain's DNS is hosted by ClouDNS, the full list of NS records found via Cloudflare DoH, and a subset list of the nameservers that matched ClouDNS nameserver patterns.
Example use cases
Sales prospecting by DNS vendor
“I want to reach out to companies that use ClouDNS for their DNS — can you check whether acmecorp.com and rivals.io are hosted on ClouDNS so I can prioritize my outreach list?”
Pre-migration DNS vendor audit
“Before we migrate the domain shopfront.net off ClouDNS, can you confirm it's still actually hosted there and show me which nameservers are matching?”
Security vendor fingerprinting
“I'm doing a security review and need to know if targetsite.org uses ClouDNS for DNS hosting — look up its NS records and tell me if any match the ClouDNS pattern.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/cloudns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically detect whether a domain is using ClouDNS as its DNS provider. It is purpose-built for ClouDNS vendor detection (vs generic NS lookup endpoints) and returns structured match results indicating exactly which nameservers matched ClouDNS patterns. Prefer this over general DNS lookup tools when doing vendor-targeted sales prospecting, DNS migration verification, or security-focused infrastructure fingerprinting against ClouDNS specifically.
Side effects
- Domain does not exist — NS lookup returns empty or NXDOMAIN
- Cloudflare DoH unavailable — DNS resolution fails
- Domain has no NS records — inconclusive result
- Ambiguous nameserver patterns — partial matches may be misclassified
- Network timeout from Cloudflare DoH upstream
