OpenDNS

Using OpenDNS is achieved by making a configuration change in the DNS settings of a network router, on individual computers, WiFi devices, or on internal DNS servers. Once OpenDNS is configured, administrators set and manage OpenDNS's advanced features, such as Web content filtering and security, by logging in to their OpenDNS account.

It is important to understand that OpenDNS advanced settings are applied to a network and those settings are subsequently inherited by all of the computers and devices that connect to that network.

Configuring OpenDNS means that OpenDNS is being specified as the DNS server for a network, usually in place of the DNS servers provided by an ISP. As the DNS server for a network, OpenDNS receives and answers the Internet DNS requests that originate from the computers and devices connected to that network.

For Enterprise networks, configuring OpenDNS typically means using OpenDNS as the forwarders of the organization's internal DNS servers. Since internal DNS server configurations can vary between a single server to multiple servers spread across departments and office locations, specific configurations will vary.

Ultimately, configuring OpenDNS is accomplished by changing a setting within a router, computer, device, or server; regardless of whether in a home, small business or Enterprise environment.
