Dear community, A new ripe document, RIPE-501, has been published "Requirements For IPv6 in ICT Equipment". This document aims to be a guide of what to ask for exactly when IPv6 is a requirement in a tender or some contract and lists the various applicable RFCs for specific kinds of ICT equipment. The document is available on http://www.ripe.net/ripe/docs/ripe-501.html Please note that when using this document as a reference, as with any RIPE document, it might get superseded by new versions in the future. Many thanks to the authors and everybody who helped with proof reading, translation and feedback. Marco, David & Shane, co-chairs of the IPv6 working group
