To connect another computer on your network to your MacBook using an application like VNC, or to stream media from the MacBook, you need to know the internal IP address for your machine. Find the internal IP address in the Network section of the MacBook System Preferences. You can also find the internal IP by executing the “ifconfig” command from a command prompt. Use an IP finder Web site such as WhatsMyIP to find the external IP address for your network.
