Your IP address is Class A.
Class A start with 1 -127 first octet.
127 address reserved for testing.
Class B start with 128 - 191 first octet.
Class C start with 192 - 223 first octet.
Class d start with 224 - 229 First octet, reserved for multicast.
Class E start with 240 - 247 First octet, reserved for research.
The private IP addresses are:
Class A 10.0.0.0 - 10.255.255.255
Class B 172.16.0.0 - 172.31.255.255
Class C 192.168.0.0 - 192.168.255.255
These addresses you can use behind proxy and firewall.
you have choose Class A address but subnetted. you got very very large
number(2^16= 65536) of subnets with 254 host for each subnet.
You better of using Class C address on your network.
192.168.0.0 255.255.255.0 so you have 254 networks each with 254 host it is
plenty. if you choose 192.168.1.0 as your network with subnetmask
255.255.255.0.
you can use firewall internal interface as 192.168.1.254 subnetmask
255.255.255.0 .

Subject: Class A or C??
We are configuring a PIX interface with the following Address/Subnet Mask.
They are 10.9.2.3/255.255.255.0
Would this be Class A address? It is using private address space. Would the
subnet mask determine the network class?
Thank you in advance.
