Most people understand how the internet works and how it provides them with web pages to browse. In this article, we’ll go over the purpose of DNS and how to change your DNS server on a PC.
When you enter a URL link into your browser, the router sends the appropriate page from a remote server.
There is, however, more to it than meets the eye. The DNS server is one of the critical components that enable quick access to the entire internet.In this we will find way to change DNS server on PC.
What Is DNS?
Computers and browsers, unlike humans, work by interpreting numbers. A URL like https://google.com is completely unreadable to them, but we can’t imagine typing random numbers every time we want to access a website.
A DNS (Domain Name System) server bridges the human-machine divide.
It contains a list of websites and the IP addresses associated with them that the browser can use to access webpages.
When you enter a URL into the address bar, the browser first consults the DNS cache and server for the corresponding IP address, after which it retrieves the website’s contents for you.
There are several types of DNS servers. Most ISPs (Internet Service Providers) will have DNS servers that all of their users will use by default.
Even your PC has a basic DNS cache that stores frequently used and recent addresses for faster access. These DNS servers, however, are not infallible, and ISP servers can be prone to faults and bottlenecks, leading users to believe they do not have internet access.
For their convenience, your ISP’s DNS servers will also store all URL requests, storing your entire browsing history.
You can’t avoid this unless you use a VPN or a browser with a VPN built in, such as DuckDuckGo.

While DNS servers are an important part of the internet infrastructure, they are frequently targeted by hackers.
A phishing attack may use cache poisoning or DNS hijacking to redirect your DNS server to a server of their choosing or to provide you with a list of fraudulent IP addresses for existing URLs.
Your browser will then be redirected to fraudulent websites, which can lead to a variety of security breaches in your online accounts and services.
While most of these methods necessitate passing through antivirus and ISP security measures, the modernization of these attack methods means that hackers and security software are constantly trying to outperform one another.
Changing your device’s DNS settings is a step toward increased security, but it is only useful if the server you intend to use is safer than the original.
