Dear IPv6 WG mailing list members, RIPE 90 will be held in Lissabon, Portugal from 12-16 May 2025, as well as online. For any participation form you can register at https://ripe90.ripe.net/attend/register/. The IPv6 Working Group session is scheduled for Thursday 15 May from 9:00 - 10:30 (UTC+2). We are looking for presentations! Please email ipv6-wg-chair (at) ripe.net if you'd like to present. Please also state if you intend to be onsite or remote, the duration of your presentation, and a short description of it. On 14th of April we will start to decide about the agenda and see, if we still have open slots. Once we have decided on the agenda, we'll contact the presenters closer to the meeting. We expect to have a draft of the presentation about two weeks before the meeting and the final slides at least two days before our session. On behalf of the IPv6 WG co-chairs, Nico, Ray and Chris
