Sunbelt Software are now offering a new service called “ClearCloud,” that operates like OpenDNS and Google Public DNS. Simply change the default DNS server settings on your computer or router to point to ClearCloud servers and you’re all set. The difference here is that Sunbelt is in the security business and they’re actively scanning the Web 24/7 for threats. Switch to ClearCloud, and you tap into their defense network without the need to install any additional software.
“ClearCloud is part of the DNS network, and has access to every URL in the world. When you type URL in your browser and click “Go” or “Enter,” your browser sends URL to ClearCloud. ClearCloud looks it up in a table, checks it against the list of bad websites, and if it passes, sends back the numeric IP address so your browser knows where to go to get the web page. All in milliseconds. If ClearCloud discovers that it’s a bad URL, it sends back the IP address of our webpage that informs you about the malicious site.” Just add following DNS IPs: 22.214.171.124 and 126.96.36.199
