I am very new to install Pi hole in my Raspberry Pi 4 which I bought today. I installed it correctly. Changed DNS address in my Netgear Router (Nighthawk R7000). But ad is still continuing in my PC,android, Iphone & Firestick. I would highly appreciate if anyone could assist me on this.
Thanks.
Please generate a debug log with pihole -d and post the token here.
Why do you have Pi-hole assigned as its own DNS resolver?
PIHOLE_DNS_7=192.168.1.7
PIHOLE_DNS_8=192.168.1.8
I don't know why DNS 8 appeared. I have been trying to set it up for last 3-4 hours. As I told you I am very new to it.
Is there any way I can resolve it?
The problem Lise in DNS_7 (this is the IP of your Pi-hole.
Let's simplify things and get your Pi-hole working. On the web admin GUI > settings > DNS page, deselect all DNS servers other than the two Cloudflare. You don't need 8 upstream DNS servers, you only need one. Selecting both Cloudflares lets Pi-hole use either of their two public IPs.
After you make these changes, we'll check on why the clients are seeing ads.
Thanks for your prompt reply. I will deselect other now, just one inquiry, can I fill Upstream DNS Servers "Custom 1 (IPv4)" as 192.168.1.7 together?
Why do you want to do this?
I changed setting as instructed, Is there anything do I need to change after this. Sorry for continuous trouble.
These settings in the router are correct. You were previously setting Pi-hole as its own upstream DNS resolver in Pi-hole, and that was not correct.
Please upload a fresh debug log and post token here.
Looks like the Pi-hole is working properly and has received and processed the following activity in the past 24 hours:
[2020-12-28 00:17:06.593 585M] Imported 27792 queries from the long-term database
[2020-12-28 00:17:06.594 585M] -> Total DNS queries: 27792

[2020-12-28 00:17:06.594 585M] -> Unique clients: 6
Let's look at the PC first to see why there are ads on that device. From the command prompt on that client (and not via ssh or Putty to the Pi), what is the output of
nslookup pi.hole
The out put is as attached.
From the same command prompt on the PC, what is the output of this command;
nslookup flurry.com
Output as attached.
Pi-hole is correctly receiving and processing queries from that client, including blocking a known ad-serving domain that is on most blocklists. If the client is seeing ads, then either there is a browser running private or secure DNS (Chrome and Firefox have this option); and the DNS queries from the browser aren't going to Pi-hole, or the ads are from sources that cannot be blocked by Pi-hole (YouTube, Facebook, etc.).
Thanks a lot. It has been really helpful for beginners like me. I hope such high level of support continues. And Wishing you a Happy New Year.
