nmap is a great application that has many uses & features. While better know for port scanning & host identification, it can also perform host discovery by running a simple ping scan on a network. A ping scan can be ran on an individual hostname, IP, or IP range. To run a ping sweep or scan, run the following command:

nmap -sn [10.0.0.0/24 | 10.0.0.1-254 | 10.0.0.44]

For example:

nmap -sn 10.0.0.0/24

As you can see, you are returned a list of hosts on the network that responded to ping requests.
