Will changing my DNS make my internet faster?

AdGuard DNS and Control D offer robust public ad-blocking resolvers that filter known advertising and tracker domains.

Can AllFixAI configure this across our entire office or home router?

Yes. Our technicians configure router-level DNS, custom blocklists, and Wi-Fi security remotely during US business hours.
