Quick Tips
- Your ISP’s default DNS is the one your router uses automatically, but it’s often slower and less private than the public options above.
- Many people switch to Cloudflare (1.1.1.1) or Google (8.8.8.8) for better speed and reliability.
- For maximum privacy, look for resolvers that support DoH or DoT (encrypted DNS).
