DNS for AI Discovery (DNS-AID) vs DNS-Based Agent Naming (DAN)
The map lists them as complementary: sites and agents commonly implement both.
| DNS for AI Discovery DNS-AID | DNS-Based Agent Naming DAN | |
|---|---|---|
| Lifecycle step | 1 Discover: What is here, and where? | 1 Discover: What is here, and where? |
| Answers | Given a domain, where is its agent endpoint, what protocol does it speak, and how can that be verified via DNSSEC/DANE? | Given a domain, which AI agents does it publish, and how can I locate and cryptographically bind to their service endpoint using DNS alone? |
| Governed by | IETF dnsop working group Internet-Draft (individual submission track, not yet WG-adopted) | IETF Independent Submission (individual draft; not sponsored by a chartered working group; 'dawn' in the draft filename is a keyword, not a working-group name) |

When to use which
- Choose DNS for AI Discovery when your question is “Given a domain, where is its agent endpoint, what protocol does it speak, and how can that be verified via DNSSEC/DANE?” and you accept its maturity: status "Internet-Draft, Standards Track intended status", implementation prototype (Infoblox and GoDaddy joint press release).
- Choose DNS-Based Agent Naming when your question is “Given a domain, which AI agents does it publish, and how can I locate and cryptographically bind to their service endpoint using DNS alone?” and you accept its maturity: status "Active Internet-Draft (individual, -00), Intended status: Standards Track; IESG state 'I-D Exists'; expires 7 December 2026", implementation prototype.
