ie. something that does

Answer 1

An expansion and useful addition to egmackenzie's "arp -a" solution for Windows -

Windows Example searching for my iPhone on the WiFi network

(pre: iPhone WiFi disabled)

• Open Command Prompt in Admin mode (R.C. Start & look in menu)
• arp -d <- clear the arp listing!
• ping 10.1.10.255 <- take your subnet, and ping '255', everyone
• arp -a
• iPhone WiFi on
• ping 10.1.10.255
• arp -a

See below for example:

Answer 2

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.

Answer 3

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 4

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 5

for /l %%a in (254, -1, 1) do ( 
    for /l %%b in (1, 1, 254) do (
        for %%c in (20, 168) do (
            for %%e in (172, 192) do (
                ping /n 1 %%e.%%c.%%b.%%a>>ping.txt
            )
        )
    )
