I'm so stunned and deeply saddened to hear this news. Knowing him for many years, Ruben was a true pillar of many working groups, I particularly admired his patience in explaining complex issues, insightful knowledge and unwavering dedication to our community. My thoughts are with his family, friends and all who had the privilege of working with him. He will be greatly missed. Sophia Feng Nitin Walia via SubPro-IRT<subpro-irt(a)icann.xn--org> -8s7w 2025年11月5日周三 12:43 写道： This is truly heartbreaking news. Rubens was an exceptional colleague insightful, composed, and immensely knowledgeable. Working with him in SubPro, the IRT, and many other groups was both a privilege and a learning experience. His calm wisdom, technical depth, and balanced perspective enriched every discussion and left a lasting mark on all who had the honor to work with him. His passing is an immense loss to our community. My heartfelt condolences go out to his family and loved ones, may they find solace in knowing how deeply he was respected and how enduring his legacy will be.     Warm Regards Nitin Walia | Director Data Xgen Technologies (P) Limited Tel: +91-141-2554970 Fax: +91-141-2554972 LinkedIn  Twitter nitin(a)xgenplus.com | नितिन(a)xn--v1bmv2ck2cxbe5k8bf.xn--h2brj9c | https://xgenplus.com VC: https://bridge01.videomeet.in - room: nitin pwd: 10000 भाषाकीआजादी - Bridging the Digital Divide, Getting Next billion online From: "Pruis Elaine via SubPro-IRT" <subpro-irt(a)icann.org>  MailId : [151773213] To: "jeff(a)jjnsolutions.com" <jeff(a)jjnsolutions.com>,"subpro-irt(a)icann.org" <subpro-irt(a)icann.org> Subject: [SubPro-IRT] Re: Rubens Kuhl - Not of Condolence Date: 04 Nov 2025 08:45:16 PM I am stunned and so very sad to hear this news.

IRT Call 15 May
by Lars Hoffmann Nov. 4, 2025

Nov. 4, 2025

Dear IRT members, For tomorrow’s call we have two topics: Fees and Terms and Conditions. Regarding fees, attached you will find the analysis that ICANN org has undertaken on the different conditional evaluations and the fees that this is resulting in. For those evaluations that are expected to be carried out by vendors, ICANN org plans to include an estimate (CPE and Name Collision High Risk String Mitigation Plan Evaluation) or a ‘will not exceed’ amount (Geographic Names Evaluation) so that applicants can prepare accordingly, but ICANN org will only charge actual costs incurred. You can also find the updated Application Fees section with new updates in the table on page 4-6. Note that other updates were reviewed by the IRT previously. The redline IRT language can be found here: https://docs.google.com/document/d/1kUixs9Ln2qnBYCPi3yCIALiI7v47fYiGaB2rvvU… On Terms and Conditions, we are still thinking through some of the feedback we received last week and so there is no updated redline for tomorrow’s call. But we will discuss the issues raised with the goal to move the conversation forward. I am also noting that next week Thursday (22 May) we will have an IRT call on the Base Registry Agreement, and, subject to tomorrow’s discussion, I anticipate we will revisit Terms and Conditions then, too. With that, I am looking forward to tomorrow’s call. Best. Lars

Name Collision IPv6 Research Study - Public Comment
by Francisco Arias Oct. 30, 2025

Oct. 30, 2025

Dear IRT, ICANN has opened a public comment period on a research study titled "Controlled Interruption IPv6 Research Study". The study focuses on extending ICANN's "controlled interruption" mechanism, previously implemented using only the IPv4 address 127.0.53.53 into the IPv6 realm, given the growing adoption of IPv6 (> 40 % of hosts). The public comment period runs from 20 October 2025 to 22 December 2025: https://www.icann.org/en/public-comment/proceeding/name-collision-ipv6-rese… Controlled interruption is a phase in the establishment of a new generic top-level domain (gTLD) that is designed to reduce the risk of name collision. During controlled interruption, certain DNS resource records, designed to interrupt resolution processes, are temporarily published at and below the gTLD name. The content of these DNS records is intended to minimize any harm that arises from such interruption. This study produces an initial list of candidate prefixes, followed by technical tests of multiple applications on popular end-user operating systems. The aim was to identify candidate addresses where DNS lookups returning that address did not result in any unintended external network traffic. A preferred candidate that met these criteria was identified: ffff:127.0.53.53, which is the IPV6 mapping of the original IPv4 controlled interruption address. Regards, -- Francisco.
