What Is the Host File?
The host file is a simple text file that maps hostnames (like yourdomain.com) to IP addresses. Editing it allows you to manually direct your computer to a specific server without modifying DNS settings.
Steps to Edit Your Host File on macOS
Step 1: Open Finder and Select “Go”
Start by clicking the Finder icon, then go to the top menu bar and select Go.
Step 2: Open “Utilities”
From the drop-down menu, choose Utilities.
Step 3: Launch Terminal
In the Utilities window, find Terminal and double-click to open it.
Step 4: Run the Command
Once Terminal is open, enter the following command and press Return:
Copy code and paste in your terminal
sudo nano /etc/hostsThis will open the host file in the Nano text editor, where you can make your changes.
Step 5: Edit the Host File
Move the cursor to the bottom of the file using the arrow keys. Add the IP address of the server and the domain name you want to map, like so:
bash
Copy code
127.0.0.1 yourdomain.com
Once you’ve entered the details, press CTRL + O to save your changes, then hit Return. Afterward, press CTRL + X to exit Nano.
Step 6: Flush Your DNS Cache
To finalize the changes, run the following command in Terminal to flush your Mac’s DNS cache:
bash
Copy code
sudo killall -HUP mDNSResponder
You can now test the domain in your browser to ensure it’s pointing to the new server. If the site changes as expected, you’ve successfully edited your host file.
Conclusion
Editing your host file on macOS is a simple but effective way to test servers before DNS changes propagate. In just six easy steps, you can direct your Mac to any server, saving time and ensuring that your site is configured correctly before going live.
