Why change your DNS server?
Your DNS server is involved in every website you open. A better provider can give you:
- Faster page loads: lower DNS lookup times on all your devices
- More privacy: encrypted DNS and providers that do not track or sell your data
- More security: providers that block malware and phishing sites
- Ad blocking: DNS-level filtering from providers like AdGuard
