💻Netplan Simplifies DNS Configuration on Ubuntu
Easier DNS setup for Ubuntu users
TL;DR
Ubuntu-based systems can now use Netplan to easily customize DNS settings from the command line. This method works across desktops and servers, simplifying network management.
Netplan allows for streamlined DNS configuration on Ubuntu-based systems by editing a single YAML file in /etc/netplan. Users can specify Cloudflare's secure DNS addresses (1.1.1.1 and 1.0.0.1) to enhance security and performance. Proper indentation is crucial, as errors may occur with incorrect formatting. This change significantly impacts network administrators managing large-scale deployments.
Key Points

Backup the original file with 'sudo cp 00-netplan.yaml 00-netplan.yaml.bak'
Use Cloudflare's secure DNS addresses: 1.1.1.1 and 1.0.0.1 for enhanced security
Restart NetworkManager with 'sudo systemctl restart NetworkManager' after changes
Verify new settings with 'ping google.com' or 'resolvectl status | grep 'DNS'
