How this service works
TXT record of voip.<domain>: looks up the voip host under the domain you give (TXT 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> TXT DNS record exists, the content of the TXT record(s) if present, and the TTL value. If the record does not exist, it reports its absence.
Example use cases
VoIP service discovery for a domain
“Check whether acme.com has a VoIP service set up — look up the TXT DNS record for voip.acme.com and tell me if it exists and what the record says.”
Pre-call infrastructure audit
“I'm onboarding a new client at clientcorp.net — can you check their DNS to see if they have a voip subdomain TXT record configured?”
Verifying VoIP DNS before migration
“Before we migrate telephony for techstartup.io, can you confirm whether voip.techstartup.io has a TXT DNS record and what its TTL is?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/voip/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, inexpensive existence check for VoIP-related DNS TXT records on a specific domain without performing full subdomain enumeration. Prefer it over generic DNS tools when you specifically need the voip.<domain> TXT record and want a focused, single-purpose lookup at low cost ($0.01 per call).
Side effects
- Domain does not exist — returns non-existence result
- No TXT record for voip subdomain — returns empty or NXDOMAIN
- Network error reaching Cloudflare DoH — lookup fails
- Invalid domain format provided — query rejected
- Transient DNS resolution failure — retry may succeed
