An IP address is a unique string of numbers that identifies a computer on a network. A MAC address is also a unique string of numbers and letters that identifies the hardware used to connect to the internet. IP addresses change depending on network status, which can reveal valuable information while troubleshooting network problems. MAC addresses never change, so they are often used to identify a device on network.
