How this service works
Is the domain's DNS hosted by ns1? Looks up the NS records (Cloudflare DoH) and matches them against ns1'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 flag indicating whether the domain's DNS is hosted by NS1, the full list of NS records found via Cloudflare DoH, and a subset list of those nameservers that matched NS1's known patterns.
Example use cases
Sales prospecting for NS1 customers
“I'm building a list of companies that use NS1 for DNS — can you check whether techstartup.io is hosted on NS1 and show me which nameservers matched?”
Pre-migration DNS vendor audit
“Before we migrate clientdomain.com to a new DNS provider, can you confirm whether it's currently on NS1 and list the nameservers we'd need to move away from?”
Security recon on suspicious domain
“I'm investigating maliciousdomain.net as part of a threat intel review — can you tell me if it's using NS1 for DNS hosting and what nameservers it's running?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/ns1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap ($0.01) yes/no answer about whether a specific domain is using NS1 as its DNS provider, especially for sales prospecting, DNS migration audits, or security vendor identification. It uses Cloudflare DoH for reliable resolution and provides matched nameserver details, making it more informative than a raw NS lookup.
Side effects
- Domain not found or non-existent — returns no NS records and hosted=no
- NS records found but none match NS1 patterns — returns hosted=no with full nameserver list
- Cloudflare DoH lookup failure due to upstream DNS issues — may return error or empty result
- Invalid or malformed domain input — may return error response
