Well, when you use 193.200.0.0 , you are blocking the traffic only for
one host (193.200.0.0), but if you use the IP/netmask, you block the
traffic for more than one host.
In your question, you wanted to block the traffic for all the computers
with the adress 193.200.xxx.xxx , so, you need to apply the netmask to
block the traffic for all the host in it. If you only want to block the
/24 instead the /16, you only need to change your mask:
deny from 193.200.0.0/255.255.255.0 --> block computers between
193.200.0.0 to 193.200.0.255.
Would help you to understand if you try to read some about the CIDR
notation.
Nice day :)
