How this service works
CNAME record of dev.<domain>: looks up the dev 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 dev without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the dev.<domain> CNAME record exists, the actual CNAME target record(s), the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN).
Example use cases
Verify dev environment DNS setup
“I just set up a dev subdomain for my site mycompany.com — can you check if dev.mycompany.com has a CNAME record configured and what it resolves to?”
Pre-deployment DNS validation
“Before we deploy, can you confirm that dev.startup.io has a CNAME record pointing somewhere and tell me the TTL so I know if DNS has propagated?”
Audit third-party SaaS dev subdomain
“We use a third-party platform for our dev environment. Can you look up the CNAME record for dev.mybrand.com to see if it's still pointing to their servers?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/dev/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, focused existence and configuration check specifically for the dev subdomain of a domain without performing broad subdomain enumeration. It is ideal for pre-deployment validation, DNS auditing, or verifying third-party integrations at low cost ($0.01 per lookup). Prefer this over general DNS CNAME endpoints when you specifically want to check the dev host.
Side effects
- Domain does not have a dev subdomain (NXDOMAIN returned, no CNAME record exists)
- Domain is invalid or malformed (lookup fails with an error)
- Cloudflare DoH is temporarily unavailable (upstream DNS timeout or error)
- The dev subdomain exists but has an A/AAAA record rather than a CNAME (returns no CNAME data)
