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 keyboarddef 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 devicesif __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
