Ping all addresses in network, windows
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

Hope this helps
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.
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.
