# DNS for AI Discovery

> Category: Discoverability

DNS-AID publishes agent entry points in DNS itself, so discovery works before a single HTTP request is made and cannot be broken by an HTML change.

## Why it matters

It is the earliest possible point of discovery, and DNSSEC makes the answer verifiable rather than merely asserted.

## Pass criteria

ServiceMode SVCB/HTTPS records or a TXT index exist under the _agents namespace, ideally DNSSEC-signed.

## How to implement it

Goal: Publish DNS for AI Discovery (DNS-AID) records for DNS-based agent discovery

ServiceMode SVCB/HTTPS records or a TXT index exist under the _agents namespace, ideally DNSSEC-signed.
