What is DNS Cache?
The DNS cache remembers relevant pieces of information that come from previous requests for a specific DNS lookup. When you type the URL to a website into your computer, it first looks locally for the IP address before searching away. Should it find what it needs, accessing the site is speedier since there is no longer much to do. This process is known as the dns resolver and makes the DNS system to be more efficient.
Also, the Domain Name System (DNS) cache is essential to your web browsing. It is a temporary place containing IP addresses and DNS records related to the websites you open. This cache helps speed the page loading by finding such page information faster in your browser, OS, and ISP..

DNS caching does shape your web browsing experience as it stores IP addresses associated with previously visited websites thus speeding up future visits. But, you may need to clear dns cache windows if cache information becomes outdated or wrong. This will keep your browsing and everything really smooth and connected.
Time to Live (TTL) and Cache Updates
Every DNS record in the cache has a Time to Live (TTL) value. This TTL shows how long the record stays valid before needing an update. When TTL expires, the cache removes the record, and a new request is made for the latest info. This keeps the cache fresh and responsive to DNS changes.
