An Overview of DNS Filter and Its Role in the Internet

| |

The DNS is a vital component of the internet. It helps users find their way to websites by translating domain names into IP addresses, and DNS filter plays an important role in that process. DNS filter is a type of software that can be used to block certain websites from being accessed, or allow specific domains only. This article will cover the basics about DNS Filter and how it works with today’s modern world wide web.

To find the IP address for a website, your computer sends a query to one of many recursive DNS servers which will contact other DNS servers until it finds the correct information. Once found, that information is relayed back to your computer whereupon you are able to connect and load web content into the browser window.

DNS filter acts as a type of middle-man to DNS queries and can be used to block certain domains. A DNS server will see the IP address that is requesting it for information, but DNS Filter will intercept the request before sending back the content in order to decide whether or not this website should be allowed. When you ask your computer “what’s my IP?” DNS servers located around the world are queried until one response with an answer – usually from its cache since our device does not have any idea where we’re currently at geographically speaking.

The Domain Name System allows sites to be found by computers but is not specific about what kind of information it displays. DNS restrictions can filter out bad or unsafe content. DNS filter is a form of DNS security, and DNS server settings are used to restrict what can be accessed.

The DNS is a basic, fast filter that prevents users from accessing malicious web content such as sites hosting phishing kits or malware. Controls can also be applied to prevent users from visiting illegal and prohibited web content.
