It’s crucial to realize that your DNS cache will occasionally erase itself without your help. That’s because the DNS cache also stores a part known as TTL, or time to live, in addition to all the information that’s important for identifying and finding a website.

Any requests to the website during this time are handled directly from the local cache without the aid of the DNS server. 

The entry will be deleted from the cache after the TTL expires.

The locations (IP addresses) of web servers hosting pages you’ve recently visited are kept in your DNS cache. You won’t be able to access the website if the web server’s location changes before your DNS cache is updated.

Any IP addresses or other DNS records will be removed from your cache by flushing DNS. In addition to other problems, this can aid with security and internet connectivity.

You might need to clean your DNS cache if you receive a lot of HTML 404 error codes. Your computer will ask nameservers for the updated DNS information when you delete the DNS cache on your device.
