生成随机 MAC 地址的 Python 脚本

此脚本生成完全随机的 MAC 地址，不需要任何外部库。它确保 MAC 地址是本地管理和单播的。

generate_mac.py

#!/usr/bin/env python3
import random

def generate_mac():
    # First byte: ensure locally administered and unicast
    first = random.randint(0x02, 0xfe) & 0xfe  # Set bit 1, clear bit 0

    # Generate remaining 5 bytes
    remainders = [random.randint(0x00, 0xff) for _ in range(5)]

    # Combine all bytes and format as MAC
    mac_bytes = [first] + remainders
    mac_addr = ':'.join([f'{b:02x}' for b in mac_bytes])

    return mac_addr

if __name__ == '__main__':
    print(f"Random MAC: {generate_mac()}")

#!/usr/bin/env python3
import random

def generate_mac():
    # First byte: ensure locally administered and unicast
    first = random.randint(0x02, 0xfe) & 0xfe  # Set bit 1, clear bit 0

    # Generate remaining 5 bytes
    remainders = [random.randint(0x00, 0xff) for _ in range(5)]

    # Combine all bytes and format as MAC
    mac_bytes = [first] + remainders
    mac_addr = ':'.join([f'{b:02x}' for b in mac_bytes])

    return mac_addr

if __name__ == '__main__':
    print(f"Random MAC: {generate_mac()}")

如何使用

将脚本复制到文件中，例如 generate_mac.py。
使用 Python 3 运行脚本：python3 generate_mac.py。

示例输出

output.txt

Random MAC: de:bb:9c:15:6d:24

Random MAC: de:bb:9c:15:6d:24
