Criticism

Although its name suggests, OpenDNS is not open source or free software. The company can generate revenue as soon as a domain name has been entered incorrectly. In this case, the user is redirected to a separate search page appears on which advertising.

This behavior is similar to the AOL search of Alice and the Site Finder by VeriSign, which at that time was heavily criticized. OpenDNS is of the opinion that this is not comparable, since the user can voluntarily opt for these services and forwarding via the OpenDNS Control Panel is switched off.
