Eliminate ads and malware on a network-wide scale by blocking them at the DNS level! By self-hosting a DNS server, you can enhance both your privacy and security. The Technitium DNS Server is an open-source solution that serves as both an authoritative and recursive DNS server, making it an excellent choice for those looking to self-host their DNS services. It is designed to function seamlessly with little to no configuration required and includes a straightforward web console that can be accessed through any modern web browser. Many people overlook the intricacies of domain name resolution, as it operates automatically and is often too complex to comprehend. Typically, computer applications rely on the operating system's DNS resolver, which queries the DNS server provided by the ISP using the UDP protocol. While this method may suffice for the average user, it enables ISPs to monitor and control your browsing activities, even when accessing sites secured by HTTPS. Furthermore, some ISPs have the capability to redirect, block, or inject unwanted content into the websites you visit, regardless of whether you're using alternative DNS services like Google DNS or Cloudflare DNS. By utilizing a self-hosted DNS server, you regain control over your online experience and can ensure a more private browsing environment.
