Find All Active/Used IP Addresses on Your Network
There is a really neat way that you can quite easily find all active/used IP Addresses on your network without the need for any third party applications or worse, pinging each IP Address individually.
Open the Command Prompt and type in the following:
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.
GUI Based Discovery
If you’re not confident using the command prompt, there are alternative GUI based applications that you can use.
TCPNetView – No installation is required, simply double-click the executable and away it goes. It will find all active IP Addresses on the subnet you are currently connected too.

Sample output problem for me:
C:\>ping -n 1 192.168.10.1 | FIND /i “Reply” 1>>c:\ipaddresses.txt
FIND: Parameter format not correct
WinXP Pro SP3 gives me an error. I’m not sure how the number 1 gets put after “Reply” string in the command by the For loop but it does and breaks it.
ANY HELP WOULD BE NICE? seems like the FIND Comand “reply” comes back with a parameter ERROR I really would like to know how to make this work. Thanks in advance
hmmm – working fine for me.
perhaps try wrapping the quotes around “Reply” in more quotes…
e.g. find /i “”"Reply”"”
see if that makes any difference.
please I’m looking for a command that i can type the cmd+ipaddress in the dos screen then return the computer name
Maybe try:
nbtstat -A ipaddress
or check out the nslookup command.

Replace the “ with ” and it will work (just delete them from the command and type them again).
Sorry, when posting the character ” changes. So replace the ” character before and after the Reply with the double quote character. On my keyboard is above the comma ,
which command is used to show all ip in lan in cmd
That is brilliant. Thank you very much.

@me too
Your copy and paste of the command probably included smart quotes – paste your copy of the command into notepad and replace the “ ” and with ” s.
