How can I ping a range of addresses starting with A and ending with B?

Do you mean Windows command line or really MS-DOS? – Dennis May 4 '12 at 19:14

You could use a for loop to ping each IP address one at a time, but this is incredibly slow.

for /l %i in (1,1,255) do ping -n 1 192.168.0.%i | find /i "Reply"

To speed up the admittedly slow answer above, and assuming the node you seek is on the lan or a fast wan, add a timeout to the ping (20 milliseconds here):

for /l %i in (1,1,255) do ping -w 20 -n 1 192.168.0.%i | find /i "Reply"

This is useful if you don't have a proper utility and you don't have a port or want to do a broad port scan, or if the client isn't listening on any port.
