How this service works
Is the domain's DNS hosted by cloudflare registrar? Looks up the NS records (Cloudflare DoH) and matches them against cloudflare-registrar'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 yes/no indicator of whether the domain's DNS is hosted by Cloudflare Registrar, the full list of NS records retrieved via Cloudflare DoH, and a subset of matched nameservers that conform to Cloudflare Registrar nameserver patterns.
Example use cases
Sales prospecting by DNS vendor
“I'm building a prospect list of companies that use Cloudflare Registrar — can you check if acme-corp.com has its DNS hosted by Cloudflare Registrar so I know whether to pitch our migration offer?”
Pre-migration DNS provider check
“Before we start the migration project, can you verify whether clientsite.net is currently using Cloudflare Registrar for DNS, including which nameservers it's using and which ones matched?”
Security vendor fingerprinting
“I'm doing reconnaissance on targetdomain.org for a security audit — can you tell me if their DNS is hosted through Cloudflare Registrar and show me the nameservers that matched?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/cloudflare-registrar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to detect whether a domain's DNS is managed through Cloudflare Registrar (as opposed to Cloudflare CDN/proxy). Ideal for sales prospecting, vendor segmentation, migration planning, and security reconnaissance where nameserver-level hosting attribution is needed. Prefer this over generic WHOIS or NS lookups when you want a definitive yes/no with matched patterns specific to Cloudflare Registrar.
Side effects
- Domain does not exist or has no NS records — returns no match with empty nameservers
- Cloudflare DoH service unavailable — lookup fails with connectivity error
- Invalid domain format provided — returns input validation error
- Domain uses Cloudflare CDN but not Cloudflare Registrar — correctly returns no match
