Solution 1

Noone is going to write your code for you.

You can either ping every IP address in your subnet range (could take a while!) or you can limit yourself to devices that have a machine account and query Active Directory for all of the computer accounts and get their addresses from the returned objects.

Solution 2

Read the subnet mask and calculate all the IP addresses in the subnet mask you are in. Then you can either user ICMP ping (standard ping) or ARP ping to list all the valid IP addresses. ARP Ping is much reliable in a subnet setting.

You can nmap to list all the hosts
nmap -nsP 192.168.10.1/254 | grep ^Host
