MAC Address to Binary Converter

This Python script allows you to validate a MAC address and convert it from hexadecimal to binary representation.
It supports several common input formats and returns both a compact binary version and an octet-split version.

Requirements

  • Python 3.x
  • Standard module re

Features

  • Verify the correctness of the format of a MAC address
  • Supports major MAC address formats:
    • AA:BB:CC:DD:EE:FF
    • AA-BB-CC-DD-EE-FF
    • AABB.CCDD.EEFF
    • AABBCCDDEEFF
  • Converts each hexadecimal octet to binary (8 bits)
  • Print:
    • Binary version separated by :
    • Compact binary version (48 bit)

Description

check_mac(mac)

  • Verify that the entered MAC address complies with one of the formats allowed via regular expressions
  • Remove any separators (:, -, .)
  • Start binary conversion if format is valid

convert_mac(mac)

  • Split MAC address into 2-character octets
  • Converts each octet from hexadecimal to binary
  • Produces two outputs:
    • Octet-split binary version
    • Compact 48-bit binary version

main()

  • Requires MAC address input from standard input
  • Start the validation and conversion process

Example

Run the script

python mac2bin.py

Console output

MAC Address: AA:BB:CC:DD:EE:FF
Separate version: 10101010:10111011:11001100:11011101:11101110:11111111
Compact version: 101010101011101111001100110111011110111011111111
