Sunbelt Software has introduced a new free service called DNS ClearCloud . This service consists of increasing the safety of users while surfing the Web. ClearCloud service was to provide safer, more reliable and faster contact with the Internet.
ClearCloud prevents you from being able to access known bad websites, sites that will download malicious files to your computer. Even better, ClearCloud prevents you from being able to access malicious websites that you may not even know your computer is trying to access — and it prevents potentially nasty programs from "phoning home" and secretly communicating between your computer and cybercriminals.
Preferred DNS server: 220.127.116.11
Alternate DNS server: 18.104.22.168
