How does Ubuntu choose the DNS server to use?
I start an AdGuard Home on localhost last week and use the 53 port as a DNS server. However, when I check the dashboard today, I found there is no request to my local AdGuard Home 53 port. When I run nslookup lowendtalk.com, I found the Ubuntu choose to use my local network DNS server and never use the localhost DNS server.
I'm using Ubuntu 18.04, and my network interface eth0 configured uses DHCP.
I stop the systemd-resolved.service. I did not configure the /etc/network/interfaces and /etc/resolv.conf
So how does the Ubuntu choose which DNS server to use, Or just use the DNS server DHCP config?

It'll just use the DNS provided by ISP with DHCP right? You'll need to manually set the DNS
By default it uses DHCP but you can reconfigure that. On Ubuntu, I think netplan is the easiest way to do it.
