unsubnetting, so they call it

Orion82698

Confused, Do I have this right?

I see in some address in practice tests, the ip address will have a /24 after it. Now, I know that this is the class of the subnet, A = /8 , B = /16 and C = /24.

But, I still don't under stand....why?

If you are looking a exam question, and it shows 2 systems, on the same subnet, and the address of the network is 192.168.1.0. Router (gateway 192.168.1.1/24) and the 2 systems (we'll say) system1 is 192.168.1.2/24 and system2 is 192.168.1.3/24. Now, in this peritular question, it didn't show the subnet mask. Is this /24 just stating that is a class C subnetwork? Because it's 192.168.1 is the network address, and the last octet is just the node. Is that all it trying to say?

Let me know if I confused you

Thanks guys.

BTW......Transcenders is awsome!

Thanks,

/24 is an example of a short notation of the subnet mask which represents the amount of bits in the mask. As you know, /24 is a class C address mask, which is 255.255.255.0 in decimal dotted format and
11111111.11111111.11111111.00000000 in binary format. As you can see, there are 24 bits set to 1 in the mask.
