DNS is a name lookup service, like a phone book for the internet. Flushing your DNS allows your device to remove outdated entries and get new ones.
Follow these steps to flush your Android's DNS:
- Open Settings.
- Click General Management.
- Click Reset.
- Click Reset Network Settings.
Note: The above steps are for Samsung devices and may be different on other Android devices.
If you are using Google Chrome in your Android to play, there is a more thorough method of flushing DNS cache:
- Open Chrome.
- In the URL bar type in chrome://net-internals/#dns
- In the left pane click DNS.
- In the right pane click Clear host cache.
