Hello,

I am currently being taught subnetting by a MSCE. I take CCNA at night. I am almost certain he is incorrect about the broadcast addresses for the subnets. Does anyone have a site I can reference specifically were broadcasts numbers are listed next to their subnets?

The broadcast address is the last address of the subnet eg 192.168.56.0 255.255.255.0 the broadcast would be 192.168.56.255

It is the number right before the next subnet. For example if you have the following subnets 32,64,96 etc it should be like this:
subnet 32 64 96
First host 33 65
Last host 62 94
Broadcast 63 95
and so on, the following link might give you a better idea

Hmm... I still have to think that my explanation is the clearest...
<slight sarcasm>
Someone else care to say the same thing with different words?

You guys are the most awsome.

Thanks!!

My teacher was right I was backassward, but willing to change my ways.

Where I am confused again is about this:

given 10.15.17.22 /13
What is the last usable IP address for the first subnet.

I'm unclear but I believe the first usable IP maybe 10.8.0.1 and I'm very unclear on the last IP in the same subnet is something like 10.14.255.254 or 10.15.......

If the host portion is all binary 1s is that not the last address of the subnet?
I was trying to keep it simple, like me.

Unfortunately, I'm not simple, I strive to complicate most things. There is more truth to that then I care to admit.

Really I dont get it.

so what is the answer here? I'm thinking 10.15.255.254 but I'm a bit confused too.
