I am having a hard time finding instructions for changing the dns provider for my droplet. It is connected to an internal network over wireshark and want to use that network’s dns servers to resolve names instead of the digital ocean 67.207.67.3 and 67.207.67.2 so I can access internal services. All I can find is for Ubuntu 20 or earlier, none of which are consistent or seem to be workingon my Ubuntu 24.04/4 LTS server.
Side note, will doing so interfere with connecting with Digital Ocean services like my hosted posgres database?

Heya,
On Ubuntu 24.04, DNS is managed by systemd-resolved. To change your DNS servers, edit /etc/systemd/resolved.conf:
[Resolve]
DNS=<your-internal-dns-ip>
FallbackDNS=67.207.67.2 67.207.67.3
Then restart the service:
sudo systemctl restart systemd-resolved
You can verify with resolvectl status to confirm it picked up the new servers.
Your managed Postgres connection string uses a hostname that resolves publicly, so as long as your internal DNS can resolve external domains (or you keep the DO nameservers as fallback like above), it should be fine. If your internal DNS only resolves internal names and nothing else, that’s where you’d run into issues.
