Unable to configure a secondary DNS server

Network manager wasn't applying the DNS servers that I entered using "Edit Connections" -> "Wired Connection 1" -> IPv4 Settings -> Switch to "Automatic (DHCP) addresses only -> entered in DNS servers
dig @10.1.0.16 internal.address works just fine, gives me what's expected.
editing resolv.conf doesn't seem to do the trick, and just gets overwritten anyways.
nmcli shows that the correct DNS servers are being used
systemd-resolve --status shows the DNS servers as expected
again, digging the DNS servers works great.
I've tried switching to dnsmasq as a workaround, which has probably just added to my confusion. I'm not even sure what to provide as far as logs go. What do you guys need to help?

Have you tried disabling thednsmasqline in/etc/NetworkManager/NetworkManager.conf? Just comment it out with a#in front of it. Secondly, if you want stuff to stay in/etc/resolv.confyou edit the file/etc/resolvconf/resolv.conf.d/originalthen whenresolvconf -uis ran the lines are added automatically to/etc/resolv.conf

I went ahead and added the symlink and put my DNS servers into thestub-resolve.confthen restartednetwork-managerbut unfortunately behavior is the same. I can resolve external but not internal resources.

On the IPV4 tab try switching automatic DHCP to Manual so you will be using the values you enter for the DNS server IP addresses,
Here are instructions for Ubuntu 16. Should work the same for V14 and V17
