Ping all addresses in network, windows

Question

Is it possible in windows cmd line to check all of the network addresses (with ping or similar) to see which ones are taken/ have active devices:

ie. something that does something like the following:

for i = 0 to 255
    ping 192.168.1.i //Print this
end

This is psuedo code obviously. I am wondering if it is possible to do something like this in windows cmd. It would be great if you didn't need a batch file, but i understand if this is impossible.

PS. Also please mention if there is a program to do this, but it would be nice to do it in cmd.

Answer 1

Open the Command Prompt and type in the following:

FOR /L %i IN (1,1,254) DO ping -n 1 192.168.10.%i | FIND /i "Reply">>c:\ipaddresses.txt 

Change 192.168.10 to match you own network.

By using -n 1 you are asking for only 1 packet to be sent to each computer instead of the usual 4 packets.

The above command will ping all IP Addresses on the 192.168.10.0 network and create a text document in the C:\ drive called ipaddresses.txt. This text document should only contain IP Addresses that replied to the ping request.

Although it will take quite a bit longer to complete, you can also resolve the IP Addresses to HOST names by simply adding -a to the ping command.

FOR /L %i IN (1,1,254) DO ping -a -n 1 192.168.10.%i | FIND /i "Reply">>c:\ipaddresses.txt 

This is from Here

Hope this helps

I know this is a late response, but a neat way of doing this is to ping the broadcast address which populates your local arp cache.

This can then be shown by running arp -a which will list all the addresses in you local arp table.

ping 192.168.1.255 arp -a 

Hopefully this is a nice neat option that people can use.

Answer 3

Best Utility in terms of speed is Nmap.

write @ cmd prompt:

Nmap -sn -oG ip.txt 192.168.1.1-255

this will just ping all the ip addresses in the range given and store it in simple text file

It takes just 2 secs to scan 255 hosts using Nmap.

Answer 4

Provided the windows box is in the same subnet:

for /L %a in (1,1,254) do start ping 192.168.0.%a

This will complete in less than 15 seconds and

arp -a 

will return any alive host.

Fastest native way I know of in Windows.
