Linux Foundation Launches DNS-AID — Decentralized Agent Discovery via DNS, Backed by Infoblox, Cloudflare, AWS, Azure, and Google Cloud
Open-source IETF draft lets agents publish to DNS using SVCB and TXT records, then be discovered by name and domain. Infoblox contributed the Python reference implementation; major DNS providers signed on.
DNS becomes the universal lookup layer for AI agents — no central registry needed.
What is it?
DNS-AID (DNS-based Agent Identification and Discovery) is an open-source spec plus a Python reference implementation that lets organizations publish AI agent endpoints to DNS using SVCB and TXT records, then have other agents discover them by name and domain. It's structured like web hosting: each agent lives under a record on your own domain.
How does it work?
Records follow the pattern `_{agent-name}._{protocol}._agents.{your-domain}` and use SVCB (RFC 9460) with optional DNSSEC and DANE TLSA records for cryptographic trust. Protocols supported include MCP, A2A, and HTTPS. The reference implementation ships with backend adapters for AWS Route 53, Cloudflare, Infoblox NIOS, Azure DNS, Google Cloud DNS, NS1, RFC 2136 DDNS, and BIND9, plus a CLI and an MCP server for Claude Desktop.
Why does it matter?
Today agents need hardcoded URLs or vendor-specific registries (AWS Agent Registry, MCP Registry) to find each other. DNS-AID lets any domain publish its agents the way it publishes websites, with DNSSEC as the trust anchor. Linux Foundation governance gives it a vendor-neutral home, which matters as MCP and A2A traffic scale across enterprise networks.
