OK,
Here's my stab at this.  I think that maybe there is a bit of a terminology
problem here.  I suspect that what you mean is that 209.225.148.192 is the
"network" not the "mask"  IF this is the case then the mask is PROBABLY
255.255.255.192.  If this is what you mean then the following is the case:

Network		209.225.148.192
Subnet Mask		255.255.255.192
First Address		209.225.148.193 - possibly the default gateway?
User Addresses	209.225.148.194 - 209.225.148.254
Broadcast Address	209.225.148.255

The fourth octet breaks out this way:
128	64	32	16	8	4	2	1
--------------------------------------------------------------------
Mask 192
1	1	0	0	0	0	0	0

First Address 193
1	1	0	0	0	0	0	1

Last Address 254
1	1	1	1	1	1	1	0

Broadcast Address 255
1	1	1	1	1	1	1	1



Just my 2c

Subject: Is this possible


I have a friend who works for a small company part-time, they have a gateway
provided by there ISP that uses 209.225.148.193 for the IP and
209.225.148.192 for the mask all of the end users have address from
.194-253, how is this possible, because if your mask is .192 would not that
just provide you with .0, .64, .128 and .192, how is that you can use
address from .192 to .256?
