Convert mac address 48 bit python3/17/2023 ![]() ![]() What’s the best way to solve this in Python? Method 1: secrets.token_hex() Now that we have a general idea of hexadecimal numbers, let’s say you’re tasked with writing Python code to generate a random hex string. Here’s an explanation if you don’t know what a MAC address is. ![]() The above screenshot of the webpage shows an illustration of network devices and their corresponding MAC address, which is represented as hexadecimal digits delimited by colons. Therefore, if all 8 bits are “on”: 11111111, we get “f” for the first 4 bits and another “f” for the last 4 bits resulting in ff. So to represent a full byte (8 bits), we would simply use a 2-digit hexadecimal number. Each number in the binary column in the chart is displayed as a 4-bit value. ![]() This allows binary numbers to be a bit more readable, and also to save space. DecimalĪ common implementation of hexadecimal numbers is binary encoding. Referring to the chart below, we can see decimal numbers along with their corresponding binary and hexadecimal equivalents. These are 0 to 9 followed by the letters a to f. The hexadecimal numbering system uses 16 symbols to represent numbers. Traditionally we are accustomed to the decimal (base 10) system utilizing the symbols 0 to 9.īecause of the electronic nature of computing, bits and bytes are represented with the binary (base 2) system using the symbols 0 and 1. If you’re already familiar with hexadecimal numbers and just want to know how to generate a random hex string, then feel free to skip this introduction.Īs you may know, there are various ways to represent a numbering system. ![]()
