Lets say you have the mask for a 10.0.0.0 network;

10.0.0.0 255.255.248.0

So the first subnet starts from 10.0.0.1 to 10.0.7.254

This would be a total of 2046 addresses usable.

The first => 10.0.0.0
The last => 10.0.7.255

They both cannot be used, since the first is your "network address" and last is the "Broadcast address"

So in effect, you will get 2046 ip addresses.

Cheers,
Rajesh

255.255.248.0  is like a CIDR /21 , which is like a an allocation of 8 contigious Class Cs (/24)

I find a lot of the questions from yourself can be answered if you read a beginners quide to networking.   below are a selection ...........

07/22/2006 300 maximum number of host  PAQ Networking
07/22/2006 350 minimum number of bits  PAQ Networking
07/22/2006 350 the broadcast address of 168.40.8.0  
07/22/2006 subnet mark for 35 host and 2 network
07/22/2006 1 byte is equal to 8 bit or not

Any admins out there, you cant seriously say these are legitimate questions?
