Question

我最近整理了这个程序，该程序应该ping网络上的所有IP地址。有一些错误，但是错误取决于您输入的IP。谢谢！

# Import modules
import subprocess
import ipaddress

# Prompt the user to input a network address
net_addr = input("Enter a network address in CIDR format(ex.192.168.1.0/24): 
")

# Create the network
ip_net = ipaddress.ip_network(net_addr)

# Get all hosts on that network
all_hosts = list(ip_net.hosts())

# Configure subprocess to hide the console window
info = subprocess.STARTUPINFO()
info.dwFlags |= subprocess.STARTF_USESHOWWINDOW
info.wShowWindow = subprocess.SW_HIDE

# For each IP address in the subnet,
# run the ping command with subprocess.popen interface
for i in range(len(all_hosts)):
    output = subprocess.Popen(['ping', '-n', '1', '-w', '500', 
str(all_hosts[i])], stdout=subprocess.PIPE,
                              startupinfo=info).communicate()[0]

    if "Destination host unreachable" in output.decode('utf-8'):
        print(str(all_hosts[i]), "is Offline")
    elif "Request timed out" in output.decode('utf-8'):
        print(str(all_hosts[i]), "is Offline")
    else:
        print(str(all_hosts[i]), "is Online")
