AIUI:

* 192.168.1.0/24 identifies an IPv4 network with an address of 
192.168.1.0 and a network prefix of 24 bits.  The address is within the 
reserved private block 192.168.0.0/16.  The prefix corresponds to a 
class C network.

* 192.168.1.1/24 identifies an IPv4 network interface with an address of 
192.168.1.1 and a network prefix of 24.  The interface is configured to 
communicate over the 192.168.1.0/24 network.
