subnetting

when subnetting addresses can you use the actual address range where the mask is, what im saying is say that you have a 255.255.255.240 mask, could the addresses from network 225 to 238 be used, I was told that the network that includes the address the same as your mask cannot be used , is this correct ?

Hi Carl,

i can't get what your trying to ask. But the given example will work. No probs,

If u r using the network 225.0.0.0/255.255.255.240, it will give the following range,

225.0.0.0 to 225.0.0.15

225.0.0.16 to 225.0.0.31

Rgs,

Hi Carl,

The network address for this last octet will be 224 and the broadcast address will be 239

So you can use any address between 224 - 239 and 225 to 238 falls within 224 network.

HTH, if yes please rate the post.
