- On Windows:
C:\Windows\System32\drivers\etc\hosts
- On macOS/Linux:
/etc/hosts
- On Windows:
- Open the Hosts File:
- Use a text editor with administrative privileges (e.g., Notepad on Windows, or
sudo nano /etc/hosts
on macOS/Linux).

- Save the File:
- Save the changes and close the editor.
- Flush DNS Cache:
- On Windows: Open Command Prompt and type
ipconfig /flushdns
. - On macOS/Linux: Use the command
sudo dscacheutil -flushcache
(macOS) orsudo systemd-resolve --flush-caches
