Introduction to DNS
Gettting started most people need to understand DNS and how your using this in your daily life. Lets start by establishing knowlege about DNS and DNS security.
The domain name system (DNS) works like a postal code or phone book for the internet. When you type “shield53.com” into your browser, the DNS server translates the text into numbers called internet protocol (IP) address. Using the Following Example bellow you can see “shield53.com” being translated into IP Address “198.185.159.144”
When you open a web browser and go to a website, you don’t have to remember and enter a long number. Instead, you can enter a domain name like “example.com” and still end up in the right place.
DNS filtering can be used as security layer to mitigate threats and reduce risks in real time. DNS filtering is very simple technique of preventing unwanted web pages or IP addresses that seem suspicious. Once you have a DNS filter enabled, you can browse the Internet knowing that the filter will prevent you from visiting malicious websites by showing you a “block page” in your web browser
