The network address is determined by the subnet mask. You are using 24 bits
of the address as the network portion which leaves you 8 bits for the host
addressing. Since there are two addresses you cannot use, namely 10.9.2.3.0
and 10.9.2.255, this leaves you with 254 hosts possible on this subnet. This
is a subnet of the 10.0.0.0 network if you were looking at a class
designation it is a class A network. Class A networks are in the range of
0 -126 for the first octet of the address. Cisco routers will treat this as
a class A network in routing protocols unless the router is told to ignore
the class of the address.
I hope this is what you were looking for in an answer.
