Hi Gert!
IPv4 is still used, of course, as all customers still need IPv4 connectivity.
v6-only might work (if the client refuses IPCP), but we never tried that yet. So, if I understand you correctly, you simply dial-up and establish a normal DSL-connection via PPPoE (v4) and then assign an IPv6-address to the ppp-interface, right? Please excuse my probably trivial questions, but I'm pretty new to PPPoE in connection with IPv6. How exactly is the v6-address (or is it a whole prefix?) assigned at your customer's end? We would like to do some tests ourselves with IPv6-only dialup and I would like to find out wether or not I can leave out all v4-parts of the connection. If this is starting to get off-topic, I would really appreciate, if you could send me a private mail regarding this matter. TNX a lot in advance!
