I started working in the Internet industry in 1995, when I helped to start up Computel Standby BV. I supported Computel while I was a student at Universiteit Twente. Computel started in Apeldoorn (NL) as a small ISP, started the Nederland.net foundation, and has grown into a server management company with its own small datacenter.

I became a RIPE Address Policy Working Group chair in May 2007, mostly because I am interested in the future of the Internet and I like to participate in things I think are important.

In May 2008 I left Computel and started working for Max.nl, which is a web application development company. In March 2010 I started my own company. I am focusing on internet infrastructure related subjects such as IPv6, routing and security. Since October 2010 I have been doing IPv6 related projects exclusively.

comment Client access to IPv6 - estimates?
PS: I am very unhappy having to give this answer. I have been working with many companies to implement IPv6 but many ISPs just aren't doing their job and avoid taking responsibility :(

It is impossible to tell you why things 'get stuck' without more information like which equipment is used, the configuration etc.

Feel free to contact me off-list to tell me which ISP it is, I know many of them so maybe I can help :)

comment Debian up in /etc/network/interfaces not working
That is weird indeed... No idea how that can happen. Can you show the output of ip -6 addr and ip -6 route after adding the lines in /etc/network/interfaces?

PS: The default source address can be overridden manually by executing i.e. /sbin/ip -6 route add default via 2a02:898:148::1 src 2a02:898:148::211 metric 1.

The Linux kernel usually chooses the last added IPv6 address as its default source address. For IPv4 it will use the address on eth0 and not those on eth0:*. So in the config above it would probably use 94.142.242.211 and 2a02:898:148::217 by default. Maybe your firewall settings need to be adjusted for that.

comment ipv6 and ipv4 server preference
Apple devices use a more complicated algorithm than Happy Eyeballs. Happy Eyeballs prefers IPv6 except when it breaks or is much slower than IPv4. Apple devices measure the performance of both protocols and can prefer IPv4 if they think it might be faster. That makes them less predictable though...

Can you tell us the OS if the client machine? Its behaviour sounds like an Apple device...

comment Single ipv6 from /64 subnet
Your question isn't entirely clear. I'm guessing that your proxy server is using SLAAC with privacy extensions and that you want to configure the server's address statically. Can you please try to explain what it is you are seeing?
