Clear Dns Cache
Why is the dns cache cleared?
DNS addresses are automatically given to clients from the internet service provider. But in some cases, the dns address is brought optionally. Web services with fixed ip addresses have their own dns and DNS servers of all web site addresses on the internet are different.
When a client (computer) connects to the internet, it keeps the DNS address it receives from the service provider in its memory. It does not request a DNS address from the service provider again for this DNS address it has stored in its memory, but sometimes the DNS server addresses in this memory lose its validity or the relevant website may change DNS. Although DNS problems can develop in different ways, in general, the problem of accessing a website arises either from the fact that the DNS address previously obtained by the computer has lost its validity or the DNS address of the website to be connected to is changed.
For this reason, there are some difficulties in accessing websites from time to time. To fix this problem, it will be enough to perform the following application and thus perform the DNS Cache Clear operation. With this application, your computer's DNS memory will be cleared and you will get a new IP address.
