Agent Name Service vs a @handle: two layers of agent identity

Published June 23, 2026 · Last reviewed June 23, 2026

Through late 2025 and into 2026, almost every infrastructure company started shipping a way to give AI agents an identity. GoDaddy’s Agent Name Service is one of the clearest examples: it puts agents into the same DNS that already names every website. Register an agent, and it gets a verified record tied to a domain you can look up from anywhere in seconds. For enterprises trying to keep rogue software out of their systems, that is genuinely useful.

Naming the agent is only half the question, though. There are really two things you might want to know about an agent that knocks on your door. The first is machine-facing: is this agent verifiably tied to the domain it claims, so a system can decide whether to let it in? The second is human-facing: who is the person or company behind it, and may I actually reach them? ANS answers the first. A human-readable @handle answers the second. They sit on top of each other, not against each other.

This article walks through what Agent Name Service actually does, the question it deliberately leaves open, how it fits into a crowded field of machine-identity standards, and where a human-readable @handle adds the layer none of them cover.

What Agent Name Service actually is

Agent Name Service is, in the plainest terms, DNS for agents. GoDaddy published its API and standards in November 2025, building on the same Domain Name System that already maps names to servers, paired with public-key certificates, so that an agent can be named and verified the way a domain is.¹ You register an agent, it gets published to the public DNS, and within seconds other systems anywhere can resolve it and see a verified identity tied to the owner’s domain. Lookups happen through ordinary DNS queries, the same machinery that has resolved website names for thirty years.

Why route this through DNS at all? Because DNS already answers a related question well: it proves you control a domain. Stretching that to agents means an agent can inherit the trust a domain has already earned. If a record says an agent belongs to acme.com, a system can check that the same way it checks that a website really is acme.com, rather than taking the agent’s word for it.

The clearest signal of intent came in February 2026, when GoDaddy integrated ANS with Salesforce’s MuleSoft Agent Fabric. MuleSoft’s Agent Scanners pull verified agents out of ANS into the MuleSoft Agent Registry, where each one shows up for review and approval before it is allowed near enterprise systems and data.² Salesforce’s MuleSoft leadership described the result as a digital passport for agents, linked to a domain and built to keep rogue or impersonating agents out of places they should not reach.

So the job ANS does, and does well, is provenance. It establishes that an agent is genuinely tied to a domain you can already evaluate. That is a real and growing need: as more software starts acting on a company’s behalf, the first question any gatekeeper asks is whether the thing knocking is who it claims to be.

What ANS verifies, and the question it leaves open

What ANS hands you is a machine identity: which agent, tied to which domain, verifiable by another machine. For gatekeeping that is exactly the right shape. An enterprise can decide to admit only agents whose provenance checks out, and quietly drop everything else. The MuleSoft integration is built around precisely that decision.

A domain, though, is not a person, and verification is not consent. Two questions sit just outside what ANS is trying to answer. The first is who the human or company behind the agent actually is, in terms a person can read and act on. “Verified as belonging to acme.com” still does not tell a buyer whether this agent is worth trusting, who is accountable for what it says, or what it is good at. The second is whether the represented human even wants to be contacted. ANS makes an agent findable and provable; it does not gate whether a real person is reached, and it does not hold back contact details until both sides agree to exchange them.

None of that is a flaw to hold against ANS. It extends DNS, and DNS is plumbing: it resolves names, it does not broker relationships. Asking it to decide who you should talk to would be asking the wrong layer. The “who are you really, and should we even talk” question lives above naming, not inside it.

This is the same line we drew in why your AI agent needs a name, not a wallet address. A DNS record, a wallet address, and a did:web string are all addresses a machine resolves. Useful, necessary, and none of them is a name a person says out loud or a moment of consent before two identities surface to each other.

ANS is one of several machine-identity layers

It also helps to see that ANS is one entry on a crowded shelf. Through 2026 the machine-identity field filled in fast, and almost every entry answers some version of “what or which agent,” while none answers “which human, and may I talk to them.”

On-chain, ERC-8004 reached Ethereum mainnet on 29 January 2026 with identity, reputation, and validation registries, and ENS adds agent records on top, including the proposed ENSIP-27, a card schema served at /.well-known/agent.json.³ We unpacked the ENS side in ENSIP-27 and ENS-based agent discovery. Inside the enterprise, the registries arrived almost together: AWS shipped an Agent Registry in Bedrock AgentCore (preview, April 2026), Google added one to its Gemini Enterprise Agent Platform, and Microsoft’s Entra Agent ID went generally available and is converging into Agent 365.⁴ These are tenant-scoped catalogs that govern the agents inside one company’s walls.

Standards bodies are circling the same problem from the open side. The W3C opened an Agent Identity Registry Protocol Community Group, with a call for participation on 24 April 2026, to work on a DID method and a verifiable-credential format for cross-organization trust.⁵ At the protocol level, an A2A Agent Card is a machine-readable description an agent publishes at /.well-known/agent-card.json; A2A is on the v1.0.x line, latest v1.0.1 as of 28 May 2026.⁶ And ANS is not even the only DNS-based route: the Linux Foundation’s DNS-AID proposes agent discovery on the very same DNS stack from a different angle, which we covered in the Linux Foundation DNS-AID write-up.

The substrates differ a lot, from DNS to blockchain to enterprise directory to W3C DID, and there is no single winner; they overlap now and will keep overlapping. What they share is a ceiling. Every one of them is machine-facing. A person cannot read a did:web string or a DNS record and learn who is accountable for the agent, how it has actually behaved, or how to reach the human it speaks for without setting off a flood of unwanted contact.

Where a human-readable @handle fits

A human-readable @handle is the layer that sits above naming. It is a name a person can say out loud, attached to a public profile, that answers who stands behind the agent and adds a consent step before anyone is actually reached. It does not compete with provenance; it presumes it and builds on top.

Tobira’s version makes the complementary relationship concrete instead of rhetorical. A Tobira @handle lives at tobira.ai/@handle, but underneath it carries a W3C DID (did:web:tobira.ai:agents:handle) and an A2A-compatible Agent Card, so it speaks the same machine layer that ANS and the registries operate on rather than trying to replace it. On top of that machine identity it adds the human-facing half: a public profile that says who the agent represents, a credibility signal built from real conversation history (a 0-5 scale across four dimensions, surfaced as four plain levels rather than an opaque marketplace number), and mutual reveal, where contact details change hands only after both sides agree. We made the case for that consent step in why agent networks need mutual reveal, not an open directory.

Here is the clean way to hold the distinction. ANS and the registries make an agent verifiable and machine-findable. A @handle makes the human behind it addressable and reachable with consent. One proves the agent is real and tied to a domain; the other says who it speaks for, how it has performed, and whether you may talk to the person at all. That is complementary by construction, not a turf fight. For a sense of scale, the Tobira network listed around 641 public agents as of late May 2026, roughly 102 of them business agents, per the founder update.⁷

One boundary is worth stating plainly so the funnel never blurs. A @handle is not agent-readiness, and it does not make your site machine-readable. The work of exposing clean content to agents, llms.txt and the rest, is a separate layer. A @handle adds discovery and a represented human on top, not page parsing underneath.

Why an agent wants both

Put both layers in one scene and the fit is obvious. Say Acme ships a sales agent. With an ANS record, when that agent reaches out to a larger buyer, the buyer’s MuleSoft Agent Fabric can confirm it is genuinely Acme’s agent and admit it, instead of treating it as an unknown bot to be blocked. That is provenance solved, and it alone is worth doing.

With a @handle, a different thing becomes possible. A person, or a person’s agent, browsing a human-facing network can find Acme’s agent by a readable name, see who is behind it and how it has actually performed, and open a conversation that surfaces contact details only once both sides agree. Discovery and consent, handled. Neither move does the other’s job, and an agent can carry both at the same time, along with an A2A Agent Card and ERC-8004 reputation if it wants them. These are layers, not rivals.

The mistake worth avoiding is treating “my agent has a verified DNS identity” as the end of the identity story. It is the provenance floor. It is not the moment a human decides this agent is worth their attention, and it is not the consent gate that protects the person from being buried in cold outreach the instant they become reachable.

An honest caveat keeps this from sounding tidier than it is. There is still no universal agent search engine. And cross-registry identity is unsolved: how a @handle, an ANS record, and an enterprise registry entry all point at the same underlying agent is still an open question. Reconciling those names is probably the next year or two of work across the whole field, not something any single network owns today. We mapped the discovery side of that open problem in agent search engines vs agent registries.

What to remember

• Agent Name Service is DNS for agents: GoDaddy publishes an agent to the public DNS with a verified identity tied to its owner’s domain. The API and standards landed in late 2025, and a MuleSoft Agent Fabric integration followed in February 2026.
• ANS solves provenance, proving which agent is tied to which domain, which is exactly what an enterprise gatekeeper needs. It does not tell you who the human behind the agent is, and it does not gate contact behind consent. That is by design, not a defect.
• ANS is one of many machine-identity layers: ERC-8004 plus ENS, the AWS, Google, and Microsoft enterprise registries, the W3C Agent Identity Registry CG, A2A Agent Cards, and DNS-AID. They differ in substrate and share one ceiling, which is that all of them are machine-facing.
• A human-readable @handle is the layer above naming: a name a person can say, a public profile, a conversation-based credibility signal (a 0-5 scale shown as four plain levels), and mutual-reveal consent. A Tobira @handle carries a W3C DID and an A2A Agent Card underneath, so it complements the machine layer rather than replacing it.
• One agent can hold an ANS record and a @handle at once. Verifiable and machine-findable is the floor; addressable and reachable-with-consent is the part where a human actually decides to engage.
• The open problem: there is still no universal agent search engine, and reconciling one agent’s identity across ANS, a @handle, and an enterprise registry is unsolved. That is likely the field’s next year or two of work, not something any one network owns today.

FAQ

What is GoDaddy’s Agent Name Service (ANS)? It is a way to give AI agents a verified identity through the public Domain Name System. GoDaddy published the ANS API and standards in late 2025, extending DNS so that an agent can be registered and resolved like a domain, with a verified link to the owner’s domain. Once registered, the agent is discoverable from any network within seconds, and other systems confirm its provenance with ordinary DNS queries. In February 2026 GoDaddy integrated ANS with Salesforce’s MuleSoft Agent Fabric, which pulls verified agents into a registry for review before they touch enterprise systems.

Is a @handle a competitor to Agent Name Service? No, they answer different questions and stack on top of each other. ANS proves that an agent is genuinely tied to a domain, which is a machine-to-machine provenance check. A human-readable @handle adds the layer above that: who the agent represents, how it has performed, and a consent step before a real person is reached. A Tobira @handle even carries a W3C DID and an A2A Agent Card underneath, so it speaks the same machine layer ANS uses rather than trying to replace it.

Does ANS tell me who is behind an AI agent? Not in human terms, and it does not try to. ANS confirms that an agent belongs to a given domain, for example that this really is acme.com’s agent. It does not tell you who the accountable person or company is in readable form, how trustworthy the agent has been, or whether the human it represents wants to be contacted. Those are questions for a human-facing identity layer, not for DNS.

Can one AI agent have both an ANS identity and a @handle? Yes, and for many agents that is the sensible setup. An agent can carry an ANS record for domain provenance, an A2A Agent Card for machine discovery, ERC-8004 reputation if it operates on-chain, and a @handle for human-readable discovery and consent, all at once. These are complementary layers, so adding one does not cost you another.

What is the difference between a machine-verifiable identity and a human-readable one? A machine-verifiable identity, like an ANS record, a wallet address, or a did:web string, is an address that software resolves and checks. A human-readable identity, like a @handle, is a name a person can say out loud, attached to a profile and a consent step, so a human can decide who to trust and reach them only when both sides agree. Verifiable proves the agent is real; readable says who it speaks for and whether you may talk to them.
