Public bug reported: I've got a netplan file:
# cat /etc/netplan/00-static-ip.yaml # Let systemd-netword manage all devices on this system network: version: 2 renderer: networkd ethernets: enp3s0: dhcp4: no dhcp6: no bridges: br0: dhcp4: no dhcp6: no interfaces: - enp3s0 addresses: - 192.168.1.122/24 gateway4: 192.168.1.1 nameservers: addresses: - 192.168.1.1 I can do a: netplan generate netplan apply but this does not result in a configuration where my queries will be resolved by my nameserver, which happens to be mikrotik router. Instead, queries appear to be answered by the systemd-resolved on localhost and it's unclear to me what nameserver that is using to resolve queries, but I'm certain that it is not 192.168.1.1 because: host mikrotik 192.168.1.1 will return: Using domain server: Name: 192.168.1.1 Address: 192.168.1.1#53 Aliases: mikrotik has address 192.168.1.1 while host mikrotik will return Host mikrotik not found: 2(SERVFAIL) While I'm not 100% sure the root cause of this bug lies in the netplan code-base vs. either systemd-resolved or one of the myriad other tools which have complicated DNS resolution in recent years but, in practical terms, the result is that netplan does not work like the documentation suggests it should.
