Explanation

A device's physical address is its MAC (Media Access Control) address, which is represented in hexadecimal notation. A MAC address consists of 12 hexadecimal digits (0–9, A–F) typically written as six pairs separated by colons or hyphens (e.g., 00:1A:2B:3C:4D:5E). Hexadecimal is used because it compactly represents binary data - each hex digit maps to exactly 4 bits - making it human-readable while remaining technically precise.
