Simple question, but you stumbled on a hard problem.

There is no definitive answer because network stacks vary. Internal firewalls may eat your packets. Hosts may not send ping replies. Routers may throw away their ARP cache (or may have been reset recently). Et cetera.

Please read the Nmap network scanning book.

Periodically query your Router via SNMP for its ARP-Cache => You also get these systems whose admins think a ping is a security breach.

If you have more than one Router: Ask your Router for its routing-table and follow next-hops...

Loop on all possible ip's within desired range and ping them... Should be possible in every computing language.
