OpenDNS service extends the domain name system (DNS). It acts as a regular DNS server but adds an extra layer of protection for a phishing attack and content filtering. In this tutorial, I will let you know about the testing of the OpenDNS configuration. OpenDNS test determines that you have correctly configured OpenDNS settings on a computer or not. By the way, What is the DNS server? The answer is, a DNS Server converts domain names to the IP addresses. All computers/servers/web hostings have own IP address. A domain name like techprevue.com is just a mask over that IP address. There is an IP address behind techprevue.com or any other domain name. As it is difficult to remember IP addresses so domain names come into existence and DNS servers are translating domain names to corresponding IP addresses. Most of the users are using the DNS server of their Internet Service Providers (ISP). Today, third-party DNS servers like OpenDNS and Google Public DNS can be used. These options provide better security and faster internet experience.

To test OpenDNS is blocking a phishing website or not, you can open internetbadguys.com. It is a safe website but created only to test OpenDNS. If security functions working properly then internetbadguys.com will be blocked.
