What is DNS Cache? What Role Does it Play on Your PC?
The Domain Name System or DNS is a one-stop destination that your system looks up when you insert a website to visit in your URL bar. Every time you visit a newer page, the DNS finds its existence and then fetches it.
If the DNS is pinged every time you want to visit a website, it will take a long time. To save time and give you a better experience, the DNS often keeps the IP address of frequently visited websites so that it skips searching the entire internet and fetches results faster.
This speed-boosting process that tries to eliminate the process of DNS lookup is known as DNS cache.

How Might DNS Cache Turn into a Problem?
While this feature makes the entire web browsing experience faster, it might cause issues in many situations. For instance, the saved IP address becomes useless if the desired website has changed its servers for any reason.
Not to forget, many websites use dynamic IP addresses. If the cached IP address is changed, your browser cannot reach the latest website, as it will stop looking for it in the DNS and start fetching the results based on your DNS cache.
In such situations, the same feature that would have enhanced the effectiveness and speed of the internet causes hindrance in the overall experience. There are multiple issues that you might come across if the DNS cache is not regularly flushed. That is how keeping your DNS cache for a longer time might turn into a problem for you.
