Scan ip address in LAN

Get from CHATGPT

import socket, struct

# Define the IP range to scan
ip_range = '192.168.1.'
start_ip = 1
end_ip = 255

# Create an empty list to store available IPs
available_ips = []

# Loop through the range of IP addresses and attempt to connect to them
for i in range(start_ip, end_ip+1):
    ip = ip_range + str(i)
    try:
        socket.inet_aton(ip)
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.settimeout(0.1) # Set the socket timeout
        s.connect((ip, 22)) # Attempt to connect to port 20 (SSH)
        available_ips.append(ip) # Add the IP to the list if it is available
        s.close() # Close the socket
        print(ip)
    except:
        pass

# Print the available IPs
print('Available IP addresses:', available_ips)
