 ====== Port Scan Target IPs ======
+===== Ports =====
+Network ports are numbers assigned to specific services running on a computer.
+  * IP address are assigned to devices and they allow messages on the network to go to and from that specific device.
+  * Each device (with its unique IP address) will have several will have multiple port numbers assigned to specific services (small programs) running on that device (usually in the background).
+  * So IP addresses enable messages to go to and from specific devices. Port numbers allow targeting of specific services or applications within those devices.
+  * Port numbers are broken down into three main sections.
