THE MAN WHO HELPED INVENT THE INTERNET JUST RETIRED FROM GOOGLE AND NOW HE WANTS TO BUILD THE IDENTITY LAYER FOR AI AGENTS Vint Cerf spent roughly two decades as Google’s chief internet evangelist, and when he retired last week, he did not do it quietly. He walked out of one of the most powerful technology companies in the world and immediately joined a project trying to solve what he considers the most urgent infrastructure problem on the internet right now: AI agents have no reliable way to identify themselves. Cerf is now advising Innovation Labs, a subsidiary of DNS registry company Identity Digital, which has submitted a formal proposal to the Internet Engineering Task Force proposing a standard for durable AI agent identity built on existing domain name system infrastructure. The idea is called DNSid. The problem it is trying to solve is real. Right now, when an AI agent reaches out to a website, a company’s internal system, or another agent, there is no universal way to verify who or what sent that message, who authorized it, and who is accountable if it causes harm. Cerf described the situation the way he has always talked about foundational internet problems: as a challenge that needs to be addressed before it becomes structural. His involvement gives the proposal credibility that a DNS registry filing on its own would not have. Whether the IETF adopts DNSid or something like it, the fact that the man who helped wire the internet is now focused on wiring accountability into AI agents says something about how seriously the industry is starting to take the question.
