Step 1: Figure Out Network and Host Requirements
In this step, you need to do two things:
- Determine the number of hosts that do, or will,
exist on the largest segment in your network.
- Determine the maximum number of segments that you have in your network--this
will tell you how many networks, or subnets, you'll need.
If you already are dealing with an existing network, then you have a lot
of analysis ahead of you. You�ll need to perform the above two tasks,
counting hosts on each segment, and the number of segments that you have.
Remember that when you are counting hosts, each device with a connection
to the segment needs to be counted� this includes PCs, servers, routers,
servers, printers, and other devices. Remember that a segment could be
used in a logical sense, like all the ports off of a switch, or a VLAN.
To assist with the remaining 5 steps, You�ll create an imaginary network.
This network has 14 segments and the largest segment has 14 devices on
it. You�ve been assigned a single class C network number (192.168.1.0).
Now you�re ready to proceed to step 2.
