The IETF 127 meeting is scheduled to take place from 14 to 20 November 2026 in San Francisco, United States. The IETF Hackathon and IETF Codesprint will be held on 14–15 November, and introductory sessions designed to help new participants make the most of the meeting will begin on the afternoon of Sunday, 15 November, so attendees are advised to plan their travel accordingly.

The event is organised by the Internet Engineering Task Force (IETF), an open international community responsible for developing and maintaining the technical standards that support the global internet. IETF meetings function as collaborative working forums where participants engage in discussions through working groups, plenary sessions, hackathons, and informal exchanges.

IETF 127 is expected to address a wide range of technical topics, including internet protocols, routing, security, transport technologies, and emerging areas in network engineering. Participation is generally open to engineers, researchers, network operators, policymakers, and other stakeholders involved in internet standardisation.

Further details, including registration information and the official agenda, are available on the event’s official website.
