The DNS cache holds information about recently accessed domain names and IP addresses; however, this information can become outdated or corrupted, causing internet connectivity issues. If you are facing such issues, flushing the DNS cache on Android can be helpful. This post will give a quick tutorial on how to Clear DNS Cache on Android Devices, allowing you to resume normal web browsing immediately.
What is DNS Cache on Android Devices
On an Android smartphone, DNS Cache is a temporary database that saves the IP addresses of recently visited websites. When you visit a website, your device sends a request to a DNS server, which converts the domain name (such as google.com) into an IP address. (such as 188.8.131.52). When your device gets an IP address from the DNS server, it stores it in the DNS cache so that it may be easily accessed in the future.
This speeds up the process of accessing previously visited websites since your device does not have to seek up the IP address every time. However, if the DNS cache gets outdated or damaged, it might result in slow internet browsing, difficulties accessing specific websites, and other internet connectivity issues. Clearing the DNS cache on your Android smartphone might help to alleviate these issues and improve the overall efficiency of your device.
Why it is Important to Flush the DNS Cache?
It is important to flush the DNS cache since it can become outdated or damaged over time, resulting in difficulties with your internet connection, such as slow page loading times or inability to visit specific websites.
When you visit a website or use an app, your device must obtain the IP address associated with the domain name. This procedure, known as domain name resolution, entails submitting a request to a DNS server in order to get the IP address. When your device receives an IP address, it keeps it in its DNS cache. This enables your device to obtain the IP address for the same website or app without having to go through the complete domain name resolution procedure again in the future.
However, if the DNS cache becomes corrupted or out-of-date, your device may retrieve the wrong IP addresses or be unable to access specific websites. In order to retrieve the most recent DNS information from the DNS server, it is necessary to clear the DNS cache. This can help improve your internet performance, troubleshoot connectivity issues, and increase your online privacy and security.
