DNS Cache creates the temporary storage for the recent DNS lookups on the web surfing app.
In short, the DNS cache helps in speeding up the succeeding requests to the same host name.
And this improper communication can cause issues like Page Not Found and other DNS-related errors.
DNS flushing can get you out of all the possible threats of DNS cache poisoning.
In this article, we will throw light on how DNS works and what DNS flushing do.
So stick to this article until the end.
It helps in making the internet better.
Lets understand its functioning with the example of a phone book.
With the use of a phonebook, we dont need to remember every number available on it.
DNS acts in a similar way, it lets users avoid remembering the IP addresses of every website.
Your web app will request the router for the IP address.
Your router has a DNS server address stored.
Therefore, it will ask the DNS server for the IP address of that hostname.
After this process, your online window will be able to load the accurate page youre looking for.
The process is the same for every website you want to visit.
However, this request cant be completed until the domain name is converted into an IP address.
DNS Cache does the same thing for you.
It tries to speed up this process.
It manages the resolution of recently visited websites before the request is sent out to the server.
What is DNS Flushing?
DNS flushing is the process of clearing the cache that contains the temporary file.
It is a mechanism that helps a user to make all the entries in the cache invalid manually.
It clears or removes all the entries saved in the local DNS cache.records of new web addresses you visit.
All these records will be taken from the DNS server.

It can be quite a serious concern for your security.
It can be done simply by using the window command prompt.
It can surely reduce the chance of falling your sensitive information into the wrong hands.
