What is OpenDNS? - Definition from WhatIs.com
Part of the Network security glossary:

OpenDNS is the world’s largest domain name system (DNS) service provider.

The ISP-independent service  adds extra features and offers an optional cloud-based security service. OpenDNS does not require software installation and can be set with options for zero configuration or customized filtering.  Optional parental controls can filter all connected network devices. Security features include anti-phishing and anti-identity theft protection.

OpenDNS’s large caches and many server locations enable faster name retrieval. Built-in redundancy improves reliability in a self-healing network built over three continents.

OpenDNS is available as a free ad-supported service. A premium ad-free version offers customer support and the company’s Umbrella security packages on a subscription basis. The premium version also provides reports on Internet resource use.

In operation since 1996, OpenDNS supports tens of millions of users.
