Using nmap to quickly ping all hosts in an address range

At $WORK, the subnet we use for some of our workstations and test boxes was only recently setup with DHCP. Previously, we’d used IP-by-Whiteboard in the office. As a result, most of the recent machines use DHCP, but there are a few older ones still around using static ...
