How this service works
CNAME record of autoconfig.<domain>: looks up the autoconfig 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 autoconfig without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the autoconfig.<domain> CNAME record exists, the CNAME target records if present, the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN) as answered by Cloudflare DoH.
Example use cases
Email client autoconfiguration check
“Does mozilla.org have an autoconfig subdomain configured? I want to know if autoconfig.mozilla.org has a CNAME record and what it resolves to.”
Domain onboarding validation
“We're onboarding acmecorp.com and I need to verify their autoconfig subdomain is properly set up — can you check if autoconfig.acmecorp.com has a CNAME record?”
Email infrastructure audit
“I'm auditing email setup for techstartup.io — can you look up the CNAME record for autoconfig.techstartup.io and tell me the TTL and where it points?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/autoconfig/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted existence and CNAME check specifically for the autoconfig subdomain of a domain — ideal for verifying email client autoconfiguration DNS setup without doing broad subdomain enumeration. Prefer this over general DNS lookup tools when the host (autoconfig) is fixed and you just need a lightweight per-domain check.
Side effects
- Domain does not have an autoconfig subdomain (NXDOMAIN response)
- Domain name is invalid or malformed
- Cloudflare DoH upstream unavailable or timeout
- No CNAME record exists but other record types may be present at that host
