How this service works
A record of voip.<domain>: looks up the voip host under the domain you give (A 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 voip.<domain> exists as an A record, the resolved IPv4 address(es), the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN) as answered by Cloudflare DoH.
Example use cases
VoIP infrastructure presence check
“I'm doing recon on acmecorp.com — can you check whether they have a voip.acmecorp.com host configured in DNS and what IP it points to?”
Pre-migration VoIP DNS validation
“Before we cut over our phone system, can you verify that voip.ourcompany.com resolves correctly and tell me the A record and TTL?”
Vendor DNS due diligence
“We're evaluating a new telecom vendor at vendorcorp.net — can you check if they have a voip subdomain set up and what IP it resolves to?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/voip/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted existence and resolution check specifically for the voip subdomain of a domain without enumerating all subdomains. Prefer this over full subdomain enumeration tools when you only need to confirm VoIP DNS presence. It is cost-effective at $0.01 per lookup and uses Cloudflare DoH for reliable, low-latency resolution.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- voip subdomain not configured — NXDOMAIN with empty records
- Network or DoH resolver timeout — upstream Cloudflare error
- Invalid domain input — malformed query error
- Payment not processed — 402 response before lookup is performed
