How this service works
CNAME record of sftp.<domain>: looks up the sftp host under the domain you give (CNAME via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like sftp without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the sftp.<domain> CNAME record exists, the record value(s) it points to, and the TTL, as resolved by Cloudflare DNS over HTTPS.
Example use cases
Verify SFTP host before connecting
“Before I try to connect to the SFTP server at sftp.clientco.com, can you check whether that subdomain has a CNAME record and what it resolves to?”
Audit vendor domain for SFTP availability
“I need to know if our vendor domain transferpartner.io has an sftp subdomain configured — can you look up the CNAME record for sftp.transferpartner.io?”
Validate domain DNS during onboarding
“We're onboarding a new partner at globallogistics.net — can you check if sftp.globallogistics.net exists as a CNAME so we know if their file transfer endpoint is set up?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/sftp/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for whether a specific domain has an sftp subdomain configured as a CNAME, without running a full subdomain enumeration. Ideal when you already have the parent domain and just need to confirm sftp host presence and its alias target via a reliable, privacy-respecting DoH resolver.
Side effects
- Domain does not have an sftp CNAME record — returns non-existence response
- Invalid or malformed domain name input — may return error or empty result
- Cloudflare DoH upstream unavailable — lookup fails with DNS resolution error
- Domain TLD not resolvable — no records returned
