I believe

route add -net 66.150.40.0 netmask 255.255.255.0 reject

 will do the trick. Of course, if it's another /24 you will have to
change the IPs.
You can add something in access.conf to deny from them.

http://www.webdevelopersjournal.com/software/apache_more_config.html

under <Directory /home/sites/> in access.conf you will see:

order deny, allow
allow from all

under that you can add:

#sites or host to block
deny from internetseer.com
deny from webclipping.com
deny from 66.150.40

You then need to reload or restart httpd
