# dns-aaaa-via-mullvad

> dns-aaaa-via-mullvad is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).

Looks up AAAA (IPv6) DNS records for a domain using Mullvad's DNS over HTTPS resolver, returning records, TTL, response code, DNSSEC validation status, and answer time.

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-via-mullvad-c888fc7a
```

Example prompt: What AAAA records does Mullvad DNS return for example.com — include the TTL, response code, whether DNSSEC was validated, and how long the resolver took to answer?

## When to prefer this

Use this endpoint when you specifically need to see how Mullvad's privacy-focused DNS resolver answers AAAA (IPv6) queries — particularly useful for detecting Mullvad-specific filtering, split-horizon responses, or DNSSEC validation behavior. Prefer this over generic DNS lookups when comparing resolver behavior across multiple providers or investigating whether Mullvad blocks or alters IPv6 records for a domain.

## Known failure modes

- Domain does not exist: returns NXDOMAIN response code with no records
- Domain has no AAAA records: returns NOERROR with empty answer section
- Resolver error: returns SERVFAIL if Mullvad cannot resolve the domain
- Invalid domain input: may return an error or malformed response
- Network timeout: Mullvad resolver may occasionally be slow or unreachable

## How this service works

AAAA records for a domain as answered by Mullvad DNS (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.

## Output

Returns the AAAA records (IPv6 addresses) for the queried domain as answered by Mullvad's DoH resolver, along with the TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether DNSSEC was validated, and the resolver's answer time in milliseconds.
