DNS Optimizer: Server Changer

DNS Optimizer: Server Changer is a powerful DNS changer and benchmarking tool designed for Chrome users who want faster, safer browsing. It lets you quickly switch DNS servers, run latency benchmarks, and tailor DNS settings for both Wi‑Fi and cellular connections. Note: the original app targets iPhone, iPad, and Mac, but this page describes the Chrome extension variant with the same core capabilities.

Key features include pre-configured servers such as Cloudflare DNS (1.1.1.1), Google Public DNS (8.8.8.8), Quad9 (9.9.9.9), Cisco OpenDNS, AdGuard, CleanBrowsing, Control D, and dns0.eu. You can also add custom DNS servers with DoH/DoT and IPv4/IPv6 support (Pro). The built‑in DNS benchmark helps you find the fastest server for your network, while options for ad blocking, malicious content filtering, and parental controls let you tailor your browsing privacy. For gamers, optimized DNS can reduce latency and improve responsiveness.
