ban an entire ip range from acessing my server..

I want to bann all netseer.com crawlers IP's from spidering my website, from linux firewall (iptables)..
There are over 500 different IP's from where they are access my server..
few IP's are:

67.202.22.253
67.202.23.133
67.202.24.156
67.202.24.170

how can i ban this entire IP range? and what is the range that should be banned? it is 67.202.0.0-67.202.255.255 or ..?

67.202.22.0/24 means 67.202.22.0-67.202.22.225 ?

Yes a /24 is 255 ip addresses or a Class C range.
/32 is 1 ip address it's a bitmask number
