If your definition of something being up is a port being open, then that's
one thing, but otherwise a ping scan "-sP" will do what you want

Take care,

Perhaps this is already in nmap and I haven't figured out how to do it yet.

Could someone add an option to perform do the following.

Ping a host, if the host is down move forward with a port scan. If an open
port is identified stop scanning that host and move onto the next one in the
list. Basically a really fast discovery scan that only notes if the host is
up. Is there any way to achieve this type of scan with nmap right now? I
don't want to identify open ports, just scan until it finds an open port on
a host, then note the host is alive and move onto the next host.

This would be extremely helpful in performing large discovery scans on huge
networks.
