Is there any network problem on your Android device, such as DNS resolution issues, slow network speeds, or wrong IP addresses? A solution is there that will help you in resolving the problems. The DNS cache can hold information about the IP addresses & domain names that were accessed recently. However, this information can get corrupted or become outdated, leading to internet connectivity issues. When you experience this kind of problem, you have to flush the DNS cache on your Android device. We will let you know how to Clear DNS Cache on Android in this article.

What Is DNS Cache On Android Devices?

It refers to a temporary database saving IP addresses of websites you have visited recently on an Android mobile. As soon as you visit a website, your Android device sends a request to a DNS server. Later, this server’s task is to convert a domain name into an IP address. Once your Android device gets the address from the DNS server, it will store this in the DNS cache to let you access it easily in the future.

As your Android device does not need to seek up the address each time, it helps to increase the speed of the procedure of accessing previously visited websites. When the DNS cache gets outdated or corrupted, you can experience slow internet browsing. In addition, it can let you face challenges when you try to access specific websites, or it might result in internet connectivity problems. Hence, you need to clear the DNS cache to alleviate the problems and improve the device’s overall efficiency.
