# dns-aaaa-voip-subdomain

> dns-aaaa-voip-subdomain is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Looks up the AAAA (IPv6) DNS record for the voip subdomain of a given domain using Cloudflare DoH, returning existence status, records, and TTL.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dns-aaaa-voip-subdomain-8d8956f7
```

Example prompt: Can you check whether voip.acme.com has an IPv6 DNS record configured — I want to know if the AAAA entry exists and what its TTL is?

## When to prefer this

Use this endpoint when you specifically need to check IPv6 (AAAA) DNS configuration for the voip subdomain of a domain — for example, when auditing VoIP infrastructure, verifying IPv6 readiness, or checking whether a business has a voip host configured. Prefer this over generic DNS tools when you want a quick, single-purpose existence check for this common host pattern without enumerating all subdomains.

## Known failure modes

- Domain does not exist — returns NXDOMAIN or no record found
- voip subdomain has no AAAA record (only A record exists) — returns empty result
- Malformed or invalid domain input — may return error or empty response
- Cloudflare DoH upstream timeout or temporary failure — request may fail
- Network connectivity issues to the DNS resolver — service unavailable

## How this service works

AAAA record of voip.<domain>: looks up the voip host under the domain you give (AAAA 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> AAAA record exists, the IPv6 address(es) it resolves to, and the TTL of the record. If no record exists, reports that the host is not found.
