The ANRW 2025 will be a one-day workshop held at the Meliá Castilla Hotel & Convention Center in Madrid, Spain, co-located with the IETF-123 meeting which runs from 19-25 July 2025 in the same venue.
All attendees must register for the ANRW. Registration provides for admittance to the ANRW and to the IETF welcome reception and tutorials on Sunday July 20, 2025.
Registration for in-person attendance at the ANRW costs $150 for all attendees that are not also attending the IETF-123 meeting. Registration for the ANRW is free of charge for those who have registered for in-person attendance at IETF-123 for the full week, on a day pass for the day of the workshop, or as a full-time student. The IETF registration fee is $150 for full-time students, which covers attendance at all IETF working groups, IRTF research groups, tutorials, and other sessions for the entire week, including the ANRW, so students are encouraged to attend for the entire week.
Register for ANRW 2025 and IETF-123
You do not need to register for IETF-123 in order to attend ANRW, but if you do register for IETF-123 you can add ANRW registration on the Options page at no charge. Note that an IETF Datatracker account is required to register (the registration pages will prompt you to create such an account, if you don’t have one).
At least one author of each accepted paper must register for the ANRW.
The ANRW will be streamed live and recorded. Remote participation will be available using the IETF remote participation system. You can find more details and information on how to register for remote participation on the IETF-123 meeting page.
