What is OpenDNS?

O OpenDNS is a Domain Name System (DNS) service designed to provide more security and speed when browsing the internet. It works as an alternative to traditional DNS servers, resolving domain names in a more agile and reliable way, in addition to incorporating advanced protection features against cyber threats.

One of the differentiators of OpenDNS is the use of routing Anycastwhich allows data to be directed to the data center closest to the user. This not only improves the efficiency of processing DNS requests, but also reduces latency and improves overall connection performance.

This service caters to both home and business users, offering features such as parental controls, blocking malicious websites and protection against phishing attacks. These features make OpenDNS an indispensable tool for anyone looking for a safer and more efficient online experience.

How does OpenDNS work?

OpenDNS acts as an intermediary between the user’s device and the servers that store data from the websites visited. When you try to access a website, OpenDNS translates the domain name (such as “example.com”) into the corresponding IP address, ensuring speed and accuracy in this process.

Unlike other DNS services, OpenDNS combines security technologies, such as filters against malware and fraudulent websites, with the aim of protecting users while they browse. Furthermore, the possibility of customizing DNS settings is a strong point for those who need specific solutions.

Another aspect worth highlighting is the use of a globally distributed data center infrastructure. This ensures that DNS requests are served by the closest server, reducing response time and increasing resilience against failures or attacks in certain regions.
