How this service works
CNAME record of vpn.<domain>: looks up the vpn 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 vpn without enumerating subdomains. $0.01 per lookup.
Output
Returns whether a CNAME record exists for the vpn subdomain of the given domain, the CNAME record value(s), the TTL in seconds, and the DNS response code, as answered by Cloudflare's DNS over HTTPS resolver.
Example use cases
VPN infrastructure presence check
“Does vpn.acmecorp.com have a CNAME record configured? I want to know if Acme Corp is running a VPN endpoint under that subdomain and what it resolves to.”
Vendor security posture review
“I'm evaluating vendors for security compliance — can you check whether vpn.vendordomain.com has a CNAME record, and tell me the TTL?”
Domain migration validation
“We just migrated our VPN infrastructure — can you confirm that the CNAME record for vpn.mycompany.com is live and see what it's pointing to?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/vpn/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a targeted, low-cost existence check for the vpn CNAME record on a specific domain without doing broad subdomain enumeration. Prefer this over generic DNS tools when you specifically want CNAME data for the vpn hostname resolved via Cloudflare's DoH for consistency and privacy. Best for security research, vendor assessments, or infrastructure audits.
Side effects
- Domain does not have a vpn subdomain — returns no records with NXDOMAIN or NOERROR with empty answer
- Invalid or malformed domain name input — may return an error or empty response
- Cloudflare DoH resolver temporarily unavailable — network timeout or 5xx error
- Non-CNAME record type exists for vpn subdomain (e.g., A record only) — CNAME result will be empty
- Rate limiting or payment failure — 402 Payment Required if x402 payment not processed
