This webinar will provide an overview of the workshop sponsored by the IETF IAB, IAB Workshop on IP Address Geolocation (ipgeows), which examined how IP-based geolocation is widely used today for applications such as content delivery, compliance, and network optimization, while highlighting its inherent limitations in accuracy, reliability, and user privacy. The session will explore current industry use cases, gaps in existing geolocation mechanisms, and the architectural challenges of relying on IP addresses for location inference, as well as discuss forward-looking approaches—including alternative, privacy-preserving location signals and improved data distribution methods—that aim to better meet enterprise, regulatory, and operational needs in modern Internet environments.

MarcBlanchet-20211101

This presentation will describe the use case of deep space networking, the key considerations to deploy such a network, and its requirements. It will also describe the current plans of the space agencies and private sector for Moon and Mars deployments. It will then describe the proposed solution.  This work is being standardized in IETF by the newly formed working group called TIPTOP (Taking IP to Other Planets). A description of the working group, milestones and current work will conclude the presentation.

Guest Speaker:

Marc Blanchet is president of Viagenie, a consulting firm on Internet engineering. He has been involved in IETF for 35 years, wrote 17 RFC, co-chaired many IETF working groups, including DTN, and was an IAB member. He is the investigator of the Deep Space IP initiative which folded into the TIPTOP working group, where he is technical advisor and delegate. He is the founder of the Space Assigned Numbers Authority (SANA) which does a similar role to IANA, but for space communications standards of the CCSDS. He is currently leading the Moon networking governance group of the Interagency Operations Advisory Group (IOAG).

AIPref talk

The IETF has kicked off efforts to standardize preferences for how content is collected and processed for AI model development, deployment, and use. This webinar will dive into the scope, deliverables, and timelines of this important new work.

Details:

The IETF has started work to standardize the building blocks that allow for the expression of preferences about how content is collected and processed for Artificial Intelligence (AI) model development, deployment, and use. The work will be done at the newly created aipref (https://datatracker.ietf.org/wg/aipref/about/) working group. This talk will discuss the scope of the work, the expected deliverables and the timeline.
