Understanding the OpenDNS server address is essential for anyone looking to enhance their online security, gain more control over network content, or improve DNS resolution speed. OpenDNS, now part of Cisco, provides a robust alternative to default ISP DNS servers, offering features like phishing protection, content filtering, and detailed analytics. The correct configuration of these server addresses ensures that your network traffic is routed through their secure and optimized infrastructure.
What is OpenDNS and Why Use It
OpenDNS is a domain name system (DNS) service that translates human-friendly web addresses into IP addresses used by servers. Unlike generic ISP DNS, OpenDNS leverages a global anycast network to reduce latency and increase reliability. Users often adopt this service to protect against malware, block malicious sites, and bypass geographic restrictions on content. The primary OpenDNS server address acts as the gateway to this enhanced browsing experience.
Primary and Secondary Server Addresses
To implement the service, you need to configure your network settings with specific numerical addresses. These settings direct your device or router to query the OpenDNS infrastructure first, before falling back to other options if necessary. Having both a primary and secondary address ensures continuity; if the primary server is unreachable, the secondary takes over without disrupting your connection.
Standard Configuration for Home and Business
Preferred (Primary) DNS: 208.67.222.222
Alternate (Secondary) DNS: 208.67.220.220
These addresses are the cornerstone of the setup. By entering these digits into your operating system or router, you essentially point your device to the OpenDNS directory service. This specific configuration is widely recommended for both home users seeking safety and businesses looking for policy enforcement.
OpenDNS Security and FamilyShield Options
While the standard addresses provide robust security, OpenDNS offers specialized server address variations for different user needs. For families concerned about inappropriate content, the FamilyShield service utilizes distinct DNS addresses that automatically filter out explicit material. This allows parents to create a safer environment without needing to configure individual device settings manually.
FamilyShield Configuration
FamilyShield Primary: 208.67.222.123
FamilyShield Secondary: 208.67.220.123
The difference between the standard and FamilyShield addresses is subtle but significant. The latter routes queries through a filter specifically designed to block domains known for adult content. This solution is popular for users who want a straightforward, no-compromise approach to web safety. Configuring the Server Address on Different Platforms The process of changing the DNS setting varies depending on the operating system or network hardware in use. On Windows, it involves modifying the adapter properties through the control panel. MacOS users adjust the settings in System Preferences, while Linux distributions often require editing network manager files or using command-line utilities. Routers typically have a web interface where these addresses can be entered once, protecting all connected devices simultaneously.
Configuring the Server Address on Different Platforms
Router Configuration Example
Accessing the router admin panel usually requires entering an IP address like 192.168.1.1 into a web browser. Once logged in, the DNS section—often under "Internet" or "WAN" settings—allows you to override the ISP's servers. Pasting the OpenDNS address into the primary field and the secondary field ensures the entire home network benefits from the service immediately, eliminating the need to configure each device individually.
