Hi I am really confusing in subnetting as more and more i go through books.
My basic question is when subnetting is done( i know bit). It is basically splitting the main net work.say
subnet mask 255.255.255.192
This will give 4 subnets
(192.168.2.0, 192.168.2.64,192.168.128 and 192.168.2.192.)
Lets say these network id's and host will be assigned by DHCP.
Now my question is how many NIC i need and where those will be hooked up. Does it need four NIC or just one (for 192.168.2.0, because we are just splitting this).
How it works in real environment. or it is done through L2 switches. Is subnetting works at Layer 2 or layer 3. Whole lot of confusion, in theory it look quite good. How a host is connected throuh, is it splited through Hub/swiches. Layer 2 0r Layer 3 switches.where the NIC is from where ip address is coming.
Some simple diagrame showing NIC (important) and subnet will be appreciated.
regards and thanks
