You may have had a problem with your internet connection if you’ve used a Windows 11 PC for a while. This is a highly frequent occurrence with several potential causes. One possible suspect could be a DNS cache that has become corrupted or contains excessively long entries.
The DNS is a database containing the addresses of every website. It links a domain name to an Internet Protocol address so that you may access a certain website. Windows 11 computers often save a DNS cache, which allows them to rapidly connect to websites by remembering the domain name associated with a specific IP address. An integral element of the internet’s infrastructure, DNS caches are prone to corruption and data accumulation over time, which may slow down performance and even cause connection problems.

Learn About DNS Cache and Why You Should Delete It.
Typing a website’s address (or URL) into a browser is the most common way to visit any site. Computers may utilize the appropriate IP address if they don’t “understand” URLs. Your computer accesses a Domain Name System (DNS) server, which maintains a database of domain names and their associated IP addresses, whenever you do a web search.
DNS lookup is necessary. However, constantly seeking an IP address could be more efficient, particularly for frequently visited sites. Therefore, the computer stores a copy of the DNS in a local cache called the Domain Name System (DNS).
On typing the URL into the browser, it will start checking the resolver cache to see if it already knows about it.
When the DNS resolver cache becomes outdated or faulty, it might disrupt the network connection. You should regularly clear the DNS cache to avoid the potential danger of DNS cache poisoning.
