I have pi-hole on home LAN, 1x on raspberry pi, 1 x centos since a while, all works well, terrific system, thanks. on status see +-30/50% blocked queries
rpi
Pi-hole [v5.16.2] * FTL [v5.22]* Web Interface [v5.19]
centos is back level as certain libs not supported
Pi-hole [v5.15.3]* FTL [v5.16.3]* Web Interface [v5.18.3]
on a TV box I've noticed it shows correctly DNS rpi 192.168.1.7, centos 192.168.1.8 ALSO shows some IPV6 address there under DNS
whilst I can see adblocking works on PC, tablet on say news site, on TV box, when watching SBS on Demand TV I get ad before the newscast starts
hmm, is it the ipv6 address I see in DNS page..?
so, disabled IPV6 support on my modem/router Technicolor DJA0231:
Local Network IPV6 state: OFF
result: no longer see IPV6 host address on TV Box, no longer get ad on TB Box SBS on Demand
so I guess I have something misconfigured or am missing something ?
thanks for any pointers
I disabled my ISP IPV6, then did a clean setup of Pihole with Unbound with same Adlists as before, I'm noticing same browsing speeds and much lower block percentage. Seeing zero ads. You may not need IPV6 unless some of your devices require it.
yes, I don't think I really need IPV6 for anything here currently, so simplest solution for now will be to disable IPV6 - I think I'll re check my router settings, perhaps removing support for IPV6 on actual WAN link page rather than Local LAN page might work better - anyhow, that's something I can tinker and assess reasonably easily.
longer term, I'll try to find proper resolution, thanks for detailed explanation. I kind of understand DNS little better than I understand IPV6... anyhow, I'll try to fix properly
just thinking loud.... maybe I should let Pi-hole do DHCP instead of using router's DHCP...?
hmmm, I think I should (re think ? and) re check...
anyhow, thank you both for assistance and explanations!
DHCP is strictly an IPv4 protocol, so switching to Pi-hole's DHCP server won't change a thing in your router's IPv6 configuration.
Even with Pi-hole's IPv6 support enabled, Pi-hole would advertise its own IPv6 (SLAAC/RA), but that wouldn't stop your router from advertising its own.
Your clients would then be free to choose from any of the advertised IPv6 addresses, with a tendency to prefer the router one, and thus by-pass Pi-hole.
