扫描IP段内的使用的IP

扫描IP段内的使用的IP

方法一：命令行

命令行进入

for /L %i IN (1,1,254) DO ping -w 1 -n 1 192.168.3.%i

arp -a

方法二：python

from scapy.all import ARP, Ether, srp
import keyboard


def scan_network(ip_range):
    # 创建一个ARP请求包
    arp = ARP(pdst=ip_range)
    ether = Ether(dst="ff:ff:ff:ff:ff:ff")
    packet = ether / arp

    # 发送包并接收响应
    result = srp(packet, timeout=2, verbose=0)[0]

    # 解析响应
    devices = []
    for sent, received in result:
        devices.append({'ip': received.psrc, 'mac': received.hwsrc})

    return devices


if __name__ == "__main__":
    # 指定要扫描的网段
    target_ip_range = str(input("请输入IP（格式：192.168.20.0/23）："))
    # target_ip_range = "192.168.20.0/23"
    active_devices = scan_network(target_ip_range)
    print("Active devices in the network:")
    for device in active_devices:
        print(f"IP: {device['ip']}, MAC: {device['mac']}")
    print("按空格键退出")
    # 检查是否有按键被按下
    while True:
        if keyboard.is_pressed('space'):
            print("Exiting...")
            break

可以用pyinstaller打包成exe来处理，这个比方法一会快一点。
还有优化空间，因为目前是单线程来的
