Not everything with an IP address is a computer - I found none of these suggestions returned all active IP addresses - in fact most returned very few. My home network has a combination of wired and wireless devices and two routers, mobile phones, TV, PVR, Apple AirPort and probably a few things I have forgotten. I used the following to scan all addresses on the 192.168.1.xxx subnet:

for /L %i in (0,1,255) do ping -n 1 -w 250 192.168.1.%i>>ipaddress.txt

The resulting file ipaddress.txt contains the ping results for all addresses and I looked for those with "Received = 1" - currently 16 addresses returned a result - I only have 4 computers in the house - and they were not all on.

Angry IP scanner has command-line support, however it can not display results in the prompt. It can however write to a file that you later can display in your command prompt.

For example:

C:\Users\<NAME>\Downloads>ipscan-3.0-beta4.exe -f:range 10.0.0.10 10.0.0.20 -s -q

Initiates a scan that scans the range 192.168.1.10 - 192.168.1.20

C:\Users\<NAME>\Downloads>ipscan-3.0-beta4.exe -f:range 10.0.0.10 10.0.0.20 -s -q -o log.txt

Initiates a scan that scans the range 192.168.1.10 - 192.168.1.20 and writes the results to log.txt

type log.txt

Would then print the log file to the command prompt like so:

These are the commands for Angry IP scanner:

Pass the following arguments:
[options] <feeder> <exporter>

Where <feeder> is one of:
-f:range <Start IP> <End IP>
-f:random <Base IP> <IP Mask> <Count>
-f:file <File>

<exporter> is one of:
-o filename.txt     Text file (txt)
-o filename.csv     Comma-separated file (csv)
-o filename.xml     XML file (xml)
-o filename.lst     IP:Port list (lst)

And possible [options] are (grouping allowed):
-s  start scanning automatically
-q  quit after exporting the results
-a  append to the file, do not overwrite
