The Importance of Having a Network Diagram

I can't tell you how much time has been wasted over the years when trying to troubleshoot network issues because of poor network documentation. Regardless of the size or complexity of your network, it's always a good idea to have a showing the logical design of your network including information such as IP addressing schemes, devices, servers, etc. This not only applies to business, but also for home (yes, home).

For smaller networks (i.e.: home and small business) , it really doesn't take that long to go through the exercise of diagraming your network. It does, however, take some time to gather the information needed to generate said diagram. It's certainly better to spend that time when things are running smoothly, rather than waiting for a problem to arise. If you wait til then, it will take much longer to resolve your issue without a diagram than it would with a proper diagram.

Here is a relatively simple network design (and dare I say fairly typical for small business and even home), to give you an idea of what it could look like. 

As you can see, it doesn't have to be complex or too sophisticated. It just needs to contain the essential information. In this case, I have the IP address information for all devices documented. This will help minimize downtime in the event of a disaster, or speed up the process when it comes time to expand your network.
