What is DNS?

What is DNS filtering?
DNS filtering is a way of restricting access to certain pages for a particular reason, often content based filtering. If a website or type of website is considered to be a hazard, its IP address will be blocked by a DNS filter and user will be stopped from accessing it. Examples of sites that could be blocked include adults, gambling, efficiency sinks, or those considered to pose major malware risks.
How DNS filtering works?
When you try to open any website, a request is sent to DNS server that checks the IP address if the website exists and compare it with a list of malicious sites. DNS blockage happens when a specific website or IP address is considered to be malicious. After checking the website is loaded and it only takes fractions of seconds to do it. DNS protect you from connecting to websites known to be malicious and sites that wants to steal your personal data like login credentials etc.
