from threading import Thread
import time


def ping_single(ip):
    ip_id = randint(1, 65535)
    icmp_id = randint(1, 65535)
    icmp_seq = randint(1, 65535)
    packet = IP(dst=ip, ttl=64, id=ip_id)/ICMP(id=icmp_id, seq=icmp_seq)
    response = sr1(packet, timeout=1, verbose=0)
    if response:
        print("[+] %s is alive" % str(ip))


def ping_scan(network):
    ip_list = ip_network(network)
    for ip in ip_list:
        t = Thread(target=ping_single, args=[str(ip)])
        t.start()


if __name__ == '__main__':

    host = '10.87.51.0/24'
    t1 = time.time()
    ping_scan(host)
    t2 = time.time()
    print("[+] 本次掃描共花費 %s 秒" % (t2 - t1))

運行結果：

[+] 10.87.51.1 is alive
[+] 10.87.51.3 is alive
[+] 本次掃描共花費 9.59500789642334 秒

花費時間還是比較長，下一版考慮優化
