How this service works
Is the domain's DNS hosted by hetzner? Looks up the NS records (Cloudflare DoH) and matches them against hetzner'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 Hetzner, the full list of NS records retrieved via Cloudflare DoH, and the subset of nameservers that matched Hetzner's known nameserver patterns.
Example use cases
Sales prospecting by DNS vendor
“I'm building a list of prospects who use Hetzner infrastructure — can you check whether acmecorp.com has its DNS hosted by Hetzner and tell me which nameservers matched?”
Pre-migration DNS audit
“Before we migrate this client's DNS away from Hetzner, can you confirm that targetdomain.com is currently using Hetzner nameservers and show me exactly which ones?”
Security vendor fingerprinting
“I'm doing infrastructure reconnaissance on competitor.com — can you tell me if their DNS is hosted by Hetzner, and list the nameservers that match Hetzner's patterns?”

Endpoint

Choose this endpoint when you specifically need to detect Hetzner as a DNS hosting provider for a domain. It is purpose-built for Hetzner vendor detection using Cloudflare DoH for reliable NS resolution, making it ideal for sales enrichment, migration planning, or infrastructure auditing workflows where Hetzner identification is the goal. Use sibling endpoints for detecting other DNS providers like Cloudflare.
Side effects
- Domain does not exist or has no NS records — returns no match with empty nameserver list
- Cloudflare DoH unavailable — lookup fails with a service error
- Invalid or malformed domain input — returns an error or empty result
- Domain uses private or uncommon nameservers that superficially resemble Hetzner patterns — possible false positive
