What dns-server's are displayed when you run below one?

@deHakkelaar

You can validate on the Pi-hole host with below (I have two Pi-hole nodes):

pi@ph5b:~ $ pihole-FTL dhcp-discover
Scanning all your interfaces for DHCP servers
[..]
   dns-server: 10.0.0.2
   dns-server: 10.0.0.4

You could disable the router DHCP service and let Pi-hole take over that part:

How do I use Pi-hole's built in DHCP server (and why would I want to)?

Using Your Existing Router For Network-wide Ad Blocking You might not need to use Pi-hole's DHCP server: In many home environments, your router also functions as your DHCP server. In this case, you can often set Pi-hole to be the DNS server for your network clients in the router's DHCP (or LAN) settings page, which allows all of your network clients to block ads simply by connecting to the network. Setting it up this way is also what makes Pi-hole very powerful for network-wide ad blocking. W…

That way you could try to advertise the Pi-hole IP three times and see if that "Realme" device adds a fourth 8.8.8.8 DNS IP which seems highly unlikely ... but still:

@deHakkelaar

To fix, advertise the Pi-hole IP two or even three times as a DNS IP via your DHCP service.
For Pi-hole's own DHCP service thats as easy as:

pi@ph5a:~ $ sudo nano /etc/dnsmasq.d/10-dhcp-dns.conf
dhcp-option=option:dns-server,0.0.0.0,0.0.0.0,0.0.0.0

pi@ph5a:~ $ pihole-FTL --test
dnsmasq: syntax check OK.

pi@ph5a:~ $ sudo service pihole-FTL reload
pi@ph5a:~ $

To check:

pi@ph5a:~ $ pihole-FTL dhcp-discover
