DNS resolution not working as expected with Pi Hole

  • 772

I am running Ubuntu 20.04 and the machine is connected to my LAN via wifi.

I setup a raspberry pi hole on my local network and I want it to be my primary DNS.

The command resolvectl status looks OK to me for the wifi interface:

Link 3 (wlp111s0)
      Current Scopes: DNS              
DefaultRoute setting: yes              
       LLMNR setting: yes              
MulticastDNS setting: no               
  DNSOverTLS setting: no               
      DNSSEC setting: no               
    DNSSEC supported: no               
  Current DNS Server: 192.168.0.11     
         DNS Servers: 192.168.0.11     
                      2001:578:3f::30  
                      2001:578:3f:1::30
          DNS Domain: ~.               
                      lan

I can even even do an nslookup on the raspberry pi:

$ nslookup 192.168.0.11
11.0.168.192.in-addr.arpa   name = pi.hole.

However, when I try to ping pi.hole, it looks like it is going out to my ISP's DNS (I have no idea how it figured out my ISP's DNS servers!)

$ ping pi.hole
PING pi.hole(pi.hole (2600:8800:1300:344:2372:fc5f:b162:37d3)) 56 data bytes

I expected pi.hole to resolve to 192.168.0.11

  1. You need to configure your router DNS settings and make your pi-hole your router's primary DNS. Then all internet traffic will be routed through the pi-hole.

    Or manually change the DNS's all the computers on your network.

    If your configuration is correct, then you should be able to access http://pi.hole or your pi's ip address from any computer on you LAN.
