Due to these design limitations combined with the technological advancements, it becomes easy for the hackers to hijack the DNS lookup process and send a user to some forged website that contains malware or a website that collects sensitive personal information.ĭNS Filtering means Domain Name System Filtering is the process of filter out and prevent your access to specific domains or IP addresses. That is why it has some design limitations. The DNS system was never designed from a security point of view. One brilliant solution to protect your family from cyber threats and malicious activities is to use DNS or Content Filtering. You have understood the importance of DNS in routing the traffic to the correct user. There are always pros and cons to everything, but the only thing that matters is how you use it. You can not just shut down your internet.On getting the IP address, the user's device contacts the server of that IP address to connect and start loading the content.On getting the IP address, it is sent to the user's device, known as " resolving the domain name.".The DNS resolver matches that domain name with the IP address by getting the information from its cache or by further sending the request to an additional DNS server.When the user enters the domain in the browser bar, a DNS query is sent to the specialized webserver to solve that query, known as DNS resolver.The DNS matches the domain name with the IP address and routes the users to the exact destination so that the users do not have to memorize the complex number strings. In the internet world, DNS (Domain Name System) is responsible for routing the traffic correctly. But still, the internet is the breeding ground for malicious activities and cyber threats. These increasing security issues lead to new security improvements for user protection by tech companies. However, it also increases our security challenges. No doubt, due to technological advancement, we can easily access the internet.
The stats show that in July 2020, there were 4.57 billion active internet users in the world, encompassing 59% of the total world's population. It would not be wrong if I say that we are living in the era of the internet.
