dhclient 4.2.1-P1 does not set IPv6 DNS servers

[Andreas Meile]

Hello Andrej

See my old mail post at

https://lists.isc.org/pipermail/dhcp-users/2011-August/013553.html

about the topic of a well working IPv6 autoconfiguration with stateless 
DHCPv6.

I also had set AdvSendAdvert = on

Here I used a little bit another conf file. See link above.

BTW: You can use the 2001:db8::/32[1] block to describe something in a 
anonymized form.

In my case, there was no need to change anything in Microsoft's registry. A 
"out of the box" setuped Windows 7 immediately gets all it's necessary 
configuration parameters.
