How to Flush DNS Cache on Windows, macOS, Android, and iOS
When you browse the web, a Domain Name System (DNS) service actively translates, or "resolves," the various web addresses you encounter into a format that your Windows, Mac, Android, or iOS device understands. These addresses are then cached locally to increase speed.
However, if something changes in the meantime, your web browser may experience connection issues and some websites may not load properly. In that case, you should clear the DNS cache to force your device to look up every web address again.
On Windows and macOS, you can quickly clear DNS cache using Command Prompt, Windows PowerShell, and Terminal consoles. However, on Android and iOS, the procedure is not as straightforward and you will need to try a few methods one by one.
