My install, Pihole installed using DOH enabled. I used the following guide.
Cloudflared DOH
I triedboth using both ways, conditional forwarding or not.
The issue I am facing:
When I use no conditional forwarding, all my clien in Quesry Log is localhost
When I use conditional forwarding I get IP addresses client.
How do I get the hostbnames?
If I use regular install, not DOH, I get hostnames in client column.
Please upload a debug log and post just the token that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:
pihole -d
or do it through the Web interface:
Tools > Generate Debug Log
Since your router is handling DHCP, Pi-hole wouldn't know the names in your network by itself, it has to query a server that does.
Your debug log shows you've already enabled Conditional Forwarding to have Pi-hole query your router at 192.168.4.1 for names.
Let's see if your router knows about hostnames by asking it directly, much as Pi-hole would.
What is the result of the following commands:
nslookup 192.168.4.189 192.168.4.1
nslookup 192.168.4.208 192.168.4.1
They timed out. why would that be?
My secondary dns server running non-doh setup do show hostmanes.
What "secondary" DNS server are you running?
It's another pi-hole but not setup form doh. I am using OpenDNS family shield there.
What is your router using as upstream DNS servers?
yes, 8.8.8.8.
Should I remove that and leave it blank?
Does that mean that your router is using Pi-hole and 8.8.8.8 as its upstream DNS servers? What is your motivation for using Pi-hole as your router's upstream?
If it is using 8.8.8.8, that would allow your router to by-pass Pi-hole.
But that maybe of little relevance, as your DHCP clients would use Pi-hole for DNS anyway:
Your debug log shows your router is distributing two private IP addresses as local DNS servers (presumably your two Pi-holes):
*** [ DIAGNOSING ]: Discovering active DHCP servers (takes 10 seconds)
Scanning all your interfaces for DHCP servers
* Received 300 bytes from eth0:192.168.4.1
Offered IP address: 192.168.4.178
DHCP options:
Message type: DHCPOFFER (2)
server-identifier: 192.168.4.1
dns-server: 192.168.4.208
dns-server: 192.168.4.209
--- end of options ---
By enabling Conditional Forwarding, your Pi-hole would query your router for local hostnames, and your router would forward any query it cannot answer itself to one of its upstreams.
If it forwards to Pi-hole, that would close a DNS loop, bouncing queries back and forth between Pi-hole and your router forever, or until time-out.
In such a constellation, a time-out would likely indicate that your router doesn't know any DNS records for your local hostnames.
Switching your router to use its defaults for upstream DNS would avoid such a loop.
I'd then expect your router to answer requests for local hostnames with NXDOMAIN, proving it doesn't register DNS records for its DHCP clients.
Got it, thanks. I think it's clearer now how to set it up.
