Hi, May I ask a different, but related question: While IPv6 migration on classic networks (server farms, internet-at-home connections) is ongoing (and has been ongoing for many, many years, alas), we don't seem to make any progress with mobile data networks. My phone shows test-ipv6.com 10/10 when connected to my home wifi, when I connect via my mobile provider, I only get IPv4/CGN. For me, this has been the case for quite a while, with multiple providers. "Mobile" is important for IPv6 migration. Without IPv6 accessibility from mobile networks, the IPv6 migration unfortunately is only engineering overhead because it will never lead to an actual migration. So, what is the opinion of the working group on this one? I did ask the Dutch regulator and they didn't seem to be interested at all in making the migration work. That worries me. Are things different in other countries? Examples we can point to? Geert Jan
