I'm taking an AWS Lab to better familiarize myself with creating a VPC.
The instructions describe the example network we are to create in the lab like so:
My background is in software, not networking, so the second paragraph sent me on a hunt to refresh my networking knowledge so that I can understand more clearly what I'm creating and how it works.
I stumbled upon this excellent video on TCP/IP addressing and it states that 10.0.0.0 is a Class A network which has a default subnet mask of 255.0.0.0, but the lab I'm taking says:
The VPS itself is a Class B network in the 10.0.0.0 space...[with a subnet] of 255.255.0.0.
So what gives? How is the VPC a Class B network but it is in a Class A space (10.0.0.0)?
