How It Works

DNS presets are stored in ~/.dns_presets and applied using macOS's networksetup command with admin privileges.

Built-in Presets

• Cloudflare - 1.1.1.1, 1.0.0.1 - Fast, privacy-focused DNS
• Quad9 - 9.9.9.9, 149.112.112.112 - Blocks malware and phishing
• OpenDNS - 208.67.222.222, 208.67.220.220 - Filtering and content control

Privacy

This extension does not collect or transmit any personal data. All DNS configuration changes are applied locally using macOS built-in tools.
