  1. Press the Windows key
  2. Type "notepad" in the search field
  3. In the search results, right click Notepad and select Run as administrator
  4. From Notepad, open the following file:

Mac OS

  1. Launch Terminal
  2. Type 'sudo nano /etc/hosts' and press return
  3. Enter your local admin password
  4. Now you'll notice you're in the Nano text editor, from where you can actually edit Mac's Hosts file. As you can see, some of the TCP/IP addresses are already reflected in here against localhost and broadcasthost titles. All you need to do to input your own TCP/IP is to follow the same format
  5. Use the arrow key to move the cursor below the existing entries
  6. Use the return key to create some space below the existing records
  7. Paste in your copied or downloaded DNS entries from QxControl
  8. Save the file by pressing Ctrl + O
  9. Exit by pressing Ctrl + X
  10. In terminal, type 'sudo killall -HUP mDNSResponder' followed by Return to clear your Mac's DNS Cache and prevent any clashes between DNS and the Hosts file
