在Python中,如何确定IP地址是否是私有的？

import ipaddress

def is_private_ip(ip: str) -> bool:
    # 将输入的IP地址转换为IPv4Address对象
    ip_address = ipaddress.IPv4Address(ip)

    # 检查IP地址是否在私有地址范围内
    private_ranges = [
        ipaddress.IPv4Network('10.0.0.0/8'),    # 10.0.0.0 至 10.255.255.255
        ipaddress.IPv4Network('172.16.0.0/12'),  # 172.16.0.0 至 172.31.255.255
        ipaddress.IPv4Network('192.168.0.0/16')  # 192.168.0.0 至 192.168.255.255
    ]

    return any(ip_address in network for network in private_ranges)

# 示例
ip = '192.168.1.1'
print(is_private_ip(ip))  # 输出：True
