* name-server: advertise DNS server per https://tools.ietf.org/html/rfc6106

= Receiving Router Advertisements =

To receive and accept RAs on an interface, you need to enable it via sysctl with the following command (as root):

<pre>
sysctl -w net.ipv6.conf.eth0.accept_ra=2
</pre>

The change is not reboot-persistent, so it either needs to be redone every time or added to rc.d.
