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.

Did you enable IPv6 forwarding in the kernel?

comment IPv6 Client Service
In that case your local IPv6 router is telling your system that it is allowed to configure its own IPv6 addresses. Do you want everything on this subnet to stop autoconfiguring IPv6 addresses or just this one system?

comment lighttpd does not start at boot after enabling ipv6
Yeah, getting an address through a dynamic protocol and then putting it statically in some other configuration files sounds like a unnecessary complication. I would personally do everything statically in such a case.

comment ipv6 reverse dns not working unless +trace is specified
On my local resolver I'm seeing named[1056]: DNS format error from 2001:5c0:1400:b::9#53 resolving 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.3.0.0.0.5.1.0.c.5.0.1.0.0.2.ip6.arpa/PTR for client 127.0.0.1#52975: too many questions. Checking pcap files now...

comment How to set the order of ipv6?
Maybe you mixed up your gateway address and your preferred source address? if your source address is 2xxx:xxx:aaac:3e::1 and your default gateway is 2xxx:xxx:aaac:3e::11 then the correct command is: ip -6 route add default via 2xxx:xxx:aaac:3e::11 dev eth0 src 2xxx:xxx:aaac:3e::1 metric 1

comment How to set the order of ipv6?
The source address you are using (2xxx:xxx:aaac:3e::11) is not one of the addresses you showed in your question. And also based on the information you gave in your question you are configuring yourself (2xxx:xxx:aaac:3e::1) to be your own default gateway... That won't work. You need to put one of your own addresses as source address and use the real gateway address.

I just tried that, but when adding an address the secondary flag is not accepted. (also: check ip -6 addr help, secondary is in FLAGS not in CONFFLAGS)

comment How to set the order of ipv6?
Simon: true, but addresses in the same prefix will all have the same common prefix for all destinations that are not in the same subnet. When there are only statically configured addresses it will usually use the most recently added address.

comment flushed IPs - cannot acces to my server
The ip addr flush dev eth0 command isn't persistent across reboots. If the problem remains after restarting your server then something else is wrong.

comment IPv6 configuration - cannot ping
I'm guessing that br1 is the interface towards the virtual machines, so try to add 2001:8d8:8f3:579c::1/64 to that interface.

Nice one, well spotted!

comment IPv6 configuration - cannot ping
Your virtual server is in 2001:8d8:8f3:579c::/64 and your default gateway is in 2001:8d8:8f3:5700::/64. That can never work. Can you include a network diagram? Is the host meant to route or bridge the network?

comment How to disable AAAA lookups?
Any reason why you don't run a full resolver on localhost? That way you eliminate the dependency on other people's (seemingly) unreliable DNS resolvers altogether.
