Dear colleagues, At the meeting of ITU-T Study Group 20, in Geneva from 9-18 April, it was decided to end the work item to develop a "Reference model of IPv6 subnet addressing plan for Internet of things deployment" (Y.IPv6RefModel). We again would like to thank this working group for its contribution - both in reviewing the draft recommendation and sharing your concern about the technical merits of the proposed model. We would also like to thank our colleagues from ARIN, GSMA, the administrations of the United Kingdom, United States, Canada and Germany, and the Rapporteur and Associate Rapporteur of Question 3/20 for their contributions, advice and ongoing support in resolving this matter. The RIPE NCC of course, remains committed to promoting and supporting the deployment of IPv6, also with regards to those elements of the Internet of Things that deploy the Internet protocol. We hope to provide a more comprehensive report during this working group’s meeting at RIPE 78 in Reykjavik. Greetings from Geneva, Marco Hogewoning Senior External Relations Officer RIPE NCC
