python和c语言计算ipv6地址子网源代码，使用python脚本简直就是噩梦。。。

    # 将IPv6子网地址转换为ipaddress.IPv6Network对象
    ipv6_network = ipaddress.IPv6Network(subnet + '/' + str(prefix_length), strict=False)

    # 生成IPv6地址的生成器
    addresses = ipv6_network.hosts()

    return addresses

# 输入IPv6子网地址和前缀长度
subnet = input("请输入IPv6子网地址（不带前缀长度）：")
prefix_length = int(input("请输入前缀长度："))

# 计算IPv6子网地址并写入文件
file_path = os.path.expanduser("~/ipv6_subnet_addresses.txt")
with futures.ThreadPoolExecutor() as executor, open(file_path, "w") as file:
    results = executor.submit(calculate_ipv6_subnet, subnet, prefix_length)

    # 将结果写入文件
    for address in results.result():
        file.write(address.compressed + "\n")
