For Linux Systems

1. Edit the systemd-resolved Configuration File:

   Open the systemd-resolved configuration file for editing using a text editor like nano or vi. On most systems, this file is located at /etc/systemd/resolved.conf. You may need superuser privileges to edit this file, so use sudo:

   sudo nano /etc/systemd/resolved.conf

2. Add the Nameserver:

   In the configuration file, you can specify the DNS servers using the DNS directive. If the directive does not exist, you can add it. If it already exists, you can append additional DNS servers to it.

   [Resolve]
   DNS=23.19.53.53 23.19.52.52 2607:f5b5:3::3 2607:f5b5:2::2

   You can add multiple nameservers separated by spaces.
   
   

3. Restart systemd-resolved:

   After editing the configuration file, you should restart the systemd-resolved service for the changes to take effect:

   sudo systemctl restart systemd-resolved

4. Verify the Changes:
   You can verify that your custom nameservers are in use by querying systemd-resolved for DNS information. Use the systemd-resolve command to check:

   sudo resolvectl status
