Robust, Free DNS FTW

The Domain Name System (DNS) is a critical component of the internet that translates human-readable domain names into machine-readable IP addresses. Recursive DNS servers are used by web surfers to resolve domains, while authoritative DNS servers store and provide information about specific domains. Many ISPs underinvest in their DNS infrastructure, leading to potential slowdowns or failures. Services like OpenDNS and CloudFlare offer improved recursive and authoritative DNS services, respectively, with features such as caching, geographic distribution, and protection against malware or cyberattacks.
