I installed pi-hole on a new raspberry pi 4. I want to setup up pi-hole as a dhcp server for ipv4 and ipv6. However I get the error "no address range available for DHCPv6 request via eth0"
Do you know what's wrong? What puzzles me is that I set up pi-hole in the same network using docker on a synology nas and everything worked fine (I shut it down before starting the new one)
Actual Behaviour:
I get the error: no address range available for DHCPv6 request via eth0
and
no address range available for DHCPv6 request via wlan0
" No DHCPv6 context has been configured for this interface. Check your DHCPv6 settings.
If you do not have an upstreams IPv6 connection (use, e.g., test-ipv6.com for testing), Pi-hole does not have any address prefix it could use to build DHCPv6 addresses causing this warning on every DHCPv6 request. The solution will be to disable DHCPv6 in your Pi-hole."
thanks for the answer. I saw that explanation and the website. But even with searching for tutorials I was not able to understand what I need to do. To me it looks like an issue with the raspberry pi or pi-hole config, as I did not get the error in the docker install on my NAS. But I still don't know where to look up the dhcpv6 settings. My /etc/dhcpcd.conf looks like this:
