How this service works
CNAME record of voip.<domain>: looks up the voip 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 voip without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the voip.<domain> CNAME record exists, the CNAME target hostname(s), the TTL value, and the DNS response code — all resolved via Cloudflare DoH.
Example use cases
Verify VoIP subdomain before onboarding
“Before we set up the phone system for acme.com, can you check if voip.acme.com already has a CNAME record and what it resolves to?”
Audit competitor VoIP infrastructure
“Look up whether voip.bigcorp.com has a CNAME configured and what host it points to — I'm researching their telecom setup.”
Debug missing VoIP service connectivity
“Our VoIP service isn't connecting — can you check if voip.mycompany.com has a valid CNAME record and tell me the TTL?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/voip/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for whether a voip.<domain> CNAME record exists without running a full subdomain enumeration. Prefer this over generic DNS resolvers when you want a pay-per-use, agent-friendly API that returns structured existence and record data specifically for the common 'voip' hostname pattern via Cloudflare DoH.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- voip subdomain has no CNAME record — returns empty record set with NOERROR
- Invalid domain format in query — may return error or empty response
- Cloudflare DoH unreachable — service may time out or return upstream error
- Domain exists but voip host has A/AAAA record instead of CNAME — returns empty CNAME result
