How this service works
Is the domain's DNS hosted by tucows? Looks up the NS records (Cloudflare DoH) and matches them against tucows'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 boolean indicating whether the domain's DNS is hosted by Tucows, the full list of NS records retrieved via Cloudflare DoH, and which specific nameservers matched Tucows's known nameserver patterns.
Example use cases
Pre-migration DNS vendor audit
“I'm about to migrate a list of client domains and need to know which ones are currently on Tucows DNS — can you check if clientsite.com is hosted by Tucows and show me the nameservers?”
Sales prospecting for Tucows customers
“We're targeting companies using Tucows as their DNS provider — can you tell me if acmecorp.com is DNS-hosted by Tucows, with the matching nameservers?”
Security reconnaissance on a suspect domain
“As part of a security investigation, I need to know who hosts the DNS for suspiciousdomain.net — specifically, is it Tucows, and which nameservers matched?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/tucows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to detect whether a domain's DNS is managed by Tucows (the registrar/DNS host), such as for sales prospecting, pre-migration audits, or security investigations targeting Tucows-hosted infrastructure. It is more precise than a generic NS lookup because it applies Tucows-specific pattern matching on top of the raw NS records.
Side effects
- Invalid or non-existent domain returns an error or empty NS records
- Domain with no NS records returns a 'no' result with empty matches
- DNS lookup timeout from Cloudflare DoH results in a lookup failure
- Malformed domain input may return a validation error
- Tucows nameserver pattern list may lag behind actual Tucows infrastructure changes, causing false negatives
