Finding your computer's hostname or IP address

Mac

• Open System Preferences.
• Select Sharing.
• You'll find your Mac's hostname (ex: Johns-iMac-Pro.local) right under Computer Name.
  

Windows

• Click on the Start menu and type cmd. When you see the cmd applications in Start menu panel, click it or just press enter.
• A command line window will open. Type ipconfig and press enter.
• You'll see a bunch of information, but the line you want to look for is "IPv4 Address." The number across from that text is your local IP address (ex: 192.168.7.43).
  

Linux or Raspberry Pi

• Open a Terminal window
• Type ifconfig
• Find the current network interface (ex: 192.168.7.44)
