How this service works
Is the domain's DNS hosted by azure dns? Looks up the NS records (Cloudflare DoH) and matches them against azure-dns'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 structured response indicating whether the domain's DNS is hosted by Azure DNS (yes/no), the full list of NS records discovered via Cloudflare DoH, and which specific nameservers matched Azure DNS patterns.
Example use cases
Sales lead Azure DNS qualification
“I'm building a list of companies likely using Azure infrastructure — can you check if microsoft.com, fabrikam.com, and acme.com have their DNS hosted by Azure DNS so I can prioritize outreach?”
Pre-migration DNS provider audit
“Before we migrate our client's DNS, I need to confirm whether their domain northwindtraders.com is currently hosted on Azure DNS — can you look up their nameservers and tell me if they match Azure's patterns?”
Security vendor fingerprinting
“I'm doing recon on a target domain for a penetration test scoping exercise — can you tell me if tailspintoys.com is using Azure DNS based on its NS records?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/azure-dns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-domain check to determine if a specific domain's DNS is managed by Azure DNS for sales prospecting, infrastructure auditing, or security reconnaissance. Prefer it over the bulk Tucows equivalent when only one domain is being checked. Best suited for real-time agent workflows where vendor detection is needed on demand and cost per lookup is acceptable at $0.01 USDC.
Side effects
- Domain does not exist or has no NS records — returns empty nameserver list with 'no' verdict
- DNS lookup timeout via Cloudflare DoH — may return an error or incomplete result
- Domain input is malformed or missing — returns a 400-style error
- Azure DNS nameserver pattern list may not cover all Azure DNS variants — could produce false negatives for unusual Azure zones
