IP Addresses in Relation to the OSI Model This lesson focuses on how IP addresses fit into the OSI Model. IP addresses are logically mapped addresses that map to a physical address. IP addresses aren't mapped to a computer and can be mapped to any MAC we want, they can change and move. They are not hard encoded and are set statically. An IP address is a 32-bit binary address and is divided into four sections called octets, this is because each section has eight numbers. Participants learn how to calculate octets using a specific numerical sequence, starting with one and incrementing our way up by powers of 2.
