Using Google Public DNS
Google Public DNS is a free service allowing users to replace their ISP's domain name servers with Google's addresses (8.8.8.8, 8.8.4.4 for IPv4; 2001:4860:4860::8888, 2001:4860:4860::8844 for IPv6) to potentially improve performance and reliability. The guide provides step-by-step instructions for configuring these settings across multiple operating systems including Windows, macOS, Linux, ChromeOS, iOS, and Android, as well as routers and mobile devices. It emphasizes backing up original DNS settings before making changes and includes testing procedures to verify proper functionality after configuration.
