What is OpenDNS?
OpenDNS is a public DNS service founded in 2006 and acquired by Cisco in 2015. It was one of the first alternatives to ISP-provided DNS, offering faster resolution and optional content filtering features.

OpenDNS vs Other Public DNS
While newer services like Cloudflare (1.1.1.1) and Google (8.8.8.8) offer faster raw speed, OpenDNS remains popular for its customizable filtering features, particularly in business and family environments where content control is important.
