About

Implement DNS for AI Discovery (DNS-AID)

Publish DNS for AI Discovery (DNS-AID) records so agents can discover your agent endpoints through DNS.

Requirements

  • Publish DNS for AI Discovery (DNS-AID) records under your domain's _agents namespace, such as _index._agents.example.com or _a2a._agents.example.com
  • Use ServiceMode SVCB records, or HTTPS records for HTTPS endpoints, with alpn and endpoint connection parameters
  • Use numeric keyNNNNN SvcParamKey names for experimental DNS for AI Discovery (DNS-AID) custom parameters until they are registered
  • Sign public DNS for AI Discovery (DNS-AID) discovery zones with DNSSEC so validating resolvers return authenticated data

Example

_a2a._agents.example.com. 3600 IN SVCB 1 agent.example.com. alpn="a2a" port=443 mandatory=alpn,port

Validate

The scanner validates DNS for AI Discovery (DNS-AID) via DNS-over-HTTPS. By default, the scanner uses Cloudflare's https://cloudflare-dns.com/dns-query with automatic fallback to https://dns.google/resolve on resolver-level failures. Library callers can override the resolver with ScanOptions.dohResolverUrl (disables fallback).

Check that checks.discoverability.dnsAid.status is "pass".
