Hi,

when left on autoconfig my windows 7 clients automatically add dns 
addresses fec0:0:0:ffff::1 to 3.

I saw this already on my old Nokia 9300i phone longer time ago, looks 
like even Windows 7 clients working like defined here:

https://tools.ietf.org/id/draft-ietf-ipngwg-dns-discovery-03.txt
http://technet.microsoft.com/en-us/library/cc783049%28WS.10%29.aspx

fec0:: addresses are deprecated since longer time (but still useful 
sometimes), but I'm wondering that Microsoft still uses them.

These are not anycast addresses, this are site-local addresses with SLA 
ffff.

 > So if I add the addresses to my servers I'm set? These (auto dns 
config) behaviour has not occurred with my linux (Fedora16) clients. How 
can I enable this feature?

- store them in /etc/resolv.conf permanently
- distribute also fec0::/something prefix via router advertisement 
daemons (because otherwise, your Linux client can't connect to such 
addresses at all because of scope mismatch)
- verify, that routing works fine from client to your site-local DNS 
servers.
