1. Create a NextDNS Account

• Visit nextdns.io and sign up for a free account.
• After signing in, you'll receive a default profile with a unique ID.

2. Customize Your Profile

• Navigate to the "Settings" tab to adjust features like Ad & Tracker Blocking, Security, and Privacy.
• Add blocklists, configure allowlists, and enable features such as DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT).

3. Configure Your Devices or Router

• Access the "Setup" tab in your NextDNS dashboard for device-specific instructions.
• Set your DNS to:
  • 45.90.28.0 and 45.90.30.0 (replace with your profile-specific IPs)
• Alternatively, use https://dns.nextdns.io/YOUR-ID for encrypted DNS.

4. Verify Your Configuration

• Visit test.nextdns.io.
• Ensure the message confirms that NextDNS is active and linked to your profile.

5. Tips for Optimal Performance

• Prefer DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT) for encrypted DNS traffic.
• On mobile devices, utilize the official NextDNS app or manually set a Private DNS hostname.
• Introduce blocklists gradually to avoid potential performance issues or unintended content blocking.

6. Advanced: Using NextDNS CLI

• For advanced setups on systems like Linux or Raspberry Pi, install the nextdns CLI daemon.
• Configure it with your profile ID and run it as a background service.
