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 Debian, Dibbler, IPv6 and Bridging Woes
What exactly do you expect to see? You ask for PD (which is for routing, not bridging) and you get it. If eth1 is up it is a potential interface to sub-delegate to, if it is down it isn't. All seems according to your configuration.

comment How can I allow applications to bind to any address in a subnet assigned to an interface?
You don't assign prefixes to interfaces, you assign addresses (from the prefix that belongs to that link) to interfaces. Out of curiosity: why do you want 4722366482869645213696 addresses on one interface?

comment SSH login via IPv6 successfull while using IPv4 to the same host yields “Permission denied”
Check your iptables and ip6tables settings. It looks like you firewall IPv4 and not IPv6 (or with different rules)

comment How can I disable automatic IPv6 neighbor route advertisement on a router?
If you're not bridging then something on your CPE is sending out those Router Advertisements. The kernel doesn't do that. Usually radvd is the tool used to send them, but maybe there is some other software that does it on your box.

comment IPv6 address changed after upgrade. Why? and how can I harden my .htaccess against this?
You basically want a stateful firewall that only allows outbound connections but not incoming connections. Most home-routers have such a firewall by default, and decent business firewalls will offer this as well.

But are you sure you want to do this? You might just enable access from the whole /64.

I assume here that you have IPv6 enabled on the LAN where your desktop is connected. You are very probably using SLAAC if you haven't configured anything else. What you are seeing are probably the privacy extensions, but because you have hidden the real IPv6 addresses in your question I can't tell you for sure. Configuration details are on i.e. home.regit.org/2011/04/ipv6-privacy. Also look at /etc/sysconf
