<p>Hi there,</p>
<p>IPv6 is by definition "multi-homed", so you would do Global Unicast Addresses (GUA; Prefix 2000::/3; RFC 4291) via your router and Unique Local Addresses (ULA; Prefix fc00::/7; RFC 4193) via dnsmasq.</p>
<p>If you want to manager GUA also via dnsmasq, then you need to do DHCP-PD from dnsmasq to your router.</p>
<p>What kind of prefix do you get from your ISP? /48, /56, /60, /64?</p>
<p>Regards<br />Maddes</p>
<p> </p>

<pre>Hoping for some help/insight it my attempting to setup IPV6 DHCP; I must
not seem to be able to input the right search terms, because I keep
going around in circles.
My Setup:
ISP <> Modem <> Router <> home network
DNS/DHCP on an RPi3 (DNSMASQ/Pi-hole, behind the router).
V4 DHCP from the RPi works flawlessly.
My router is pulling V6 from the ISP via DHCP-PD, and I can't fine-tune
the routers' RA to only send out route info, and if I disable the RA
from the router, no IPV6 at all (ifconfig/ipconfig only shows link-local
addresses), no matter what I try with DNSMASQ.
IPV6 pass-through on the router has the same result.
Here is what I have from .conf files (all from pi-hole interface):
enable-ra
dhcp-option=option6:dns-server,[::]
dhcp-range=::100,::1ff,constructor:eth0,ra-names,slaac,168h
ra-param=*,high,60,0
I changed the ra-param in an attempt to bypass the routers' RA.
Option6 is working as expected.
Any ideas, or am I just looking at a pipe dream (wanting host names in
the pi-hole query log, instead of IPV6 addresses).
Thank you,
Merell Matlock</pre>
