What about the shared medium nature of DOCSIS? Do they share some infrastructure with the other cable ISPs or are these usually separate? Usually this provider is very progressive [1][2][3] and because of these positive impressions I did not suspect them to hold back the cable IPv6 rollout due to financial reasons. According to [4] they even provide OpenWRT instructions for their native IPv6 and only their cable users are left without native IPv6. :( [1] https://mirror.netcologne.de/ https://mirror.netcologne.de/ [2] https://www.sixxs.net/pops/netcologne/ https://www.sixxs.net/pops/netcologne/ [3] https://www.netaachen.de/ueber-uns/breitbandausbau https://www.netaachen.de/ueber-uns/breitbandausbau [4] https://www.netaachen.de/privatkunden/ipv6 https://www.netaachen.de/privatkunden/ipv6
