NextDNS CLI not reporting hostname

I installed NextDNS CLI on Ubuntu and pointed all my clients at it. I see in the logs it is not reporting the hostname but is reporting Device #xxxx

 

How do I get this to populate the hostname of the actual device? 

I did select "report hostnames" and "act as a router" during setup

  • Did a bit of troubleshooting and digging and figured out how to resolve this. In my case my DHCP server is located on my router, but the NextDNS CLI is running on a Ubuntu VM. I had to make a few changes to the nextdns.conf so it could look up the DHCP hostnames against my router.

    sudo vi nextdns.conf
    
    discovery-dns 192.168.X.X

    (192.168.X.X = Router / DHCP host IP)

     

    I also changed 

    listen 127.0.0.1:53

    to

    listen 192.168.X.X:53

    (192.168.X.X:53 = NextDNS CLI host IP)

  • I decided to use hosts file instead for now but still would like to be able to use this method if possible
