Best Network Documentation Software

A best-in-class network documentation software plays an important role in bridging the communication gap among a technology team as well as between teams. In order to ensure that your company’s technology (WiFi, network, network equipment) operates at peak efficiency, it is critical that you have accurate and up-to-date documentation of your networks. This way, if there are any difficulties with the WiFi, they can be resolved quickly. A detailed document also allows new team members to set up and configure equipment more easily.

There are many kinds of Network Documentation Software that you can use for your work. Network management tools help companies modernize and improve their communication protocols, computer equipment and applications. There are different types of network management software products that make easier network bandwidth monitoring, network capacity planning and manage different security risks.

Network management is the process of monitoring and maintaining computer networks, like ethernet and interconnection devices. Network management software monitors and displays information about a network’s bandwidth utilization, performance, security and inventory details. Network management also involves employing tools for fault diagnosis, configuration management, monitoring and inventory control. To achieve this, experts often purchase tools from best network documentation software free to monitor and manage network elements.

Your company’s network doesn’t just run itself and it’s important to have the right tools and know what’s actually going on. Network documentation software is less about being flashy and more about giving you exactly what you need: a place to document your network’s components, relationships, and changes so you can better manage it moving forward.

Types of software documentation. 

Documentation is a crucial part of the software. There are mainly five types of software documentation. 

  • Requirements – Identifies attributes, capabilities, characteristics, or qualities of a system. 
  • Architecture/Design – Overview of software. Includes relations to an environment and construction principles to be used in design of software components.
  • Technical – Documentation of code, algorithms, interfaces, and APIs.
  • End user – Manuals for the end-user, system administrators and support staff.
  • Marketing – How to market the product and analysis of the market demand.

Network Diagrams are essential for ensuring your have a complete understanding of how your network topology is interconnected and can give you an overhead view of whats going on in your network.

Many times, it will help you visualize where your infrastructure is lacking and what needs to be upgraded/replaced.

Having a properly documented schematic of your entire network and connections can also ensure you can troubleshoot issues in a systematic order when they arise.

The following tools will improve your documentation and presentation. Improved presentation enhances the network administrators’ ability to communicate with non-technical stakeholders in your organization and help you win the right budget for the network creation project.

1. SolarWinds Network Topology Mapper (FREE TRIAL)

SolarWinds Network Topology Mapper - Scan

The SolarWinds Network Topology Mapper includes on-demand device discovery and automated mapping. This gives you a great starting point if you are adding to an existing network. You can choose whether the discovery procedure uses SNMP or ICMP (Ping and Traceroute) to locate devices. It can also identify network infrastructure through WMI and CDP (Cisco Discovery Protocol) methods.Key Features:

  • Network autodiscovery
  • Customizable topology maps
  • Maps Hyper-V and VMWare virtualizations
  • Icon selection for different devices

The mapping discovery procedure can also plot the network infrastructure that composes virtualizations and maps clients to hosts for VMWare and Hyper-V implementations. Maps can be exported into presentation formats for distribution and it is also possible to export them into Visio for further work.

The map development environment supports different network plans and can compile several perspectives from one scan. The icon library has a suitably diverse set of device representations to enable you to distinguish between types of network equipment visually on the map. You can also adapt existing icon designs to create your own.

Solarwinds network topology mapper

If you don’t want to use an automatically-generated map, you can set the discoverer tool to just create a device inventory, from which you can plot your own topology map. An auto-update feature would not be useful for a network plan for expansion. However, you can store different maps and set your current system topology to update automatically when alterations to the existing network occur.


  • Uses auto-discover for automated mapping, great for larger more complex networks
  • Uses multiple protocols to identify network devices, ICMP, SNMP, WMI, and CDP
  • Designed to work in virtual environments and supports both VMWare and Hyper-V hosting
  • Can build static maps and include devices from your network for capacity planning and testing


  • Would like to see a longer trial period

The network mapper is compliant with PCI and FIPS-2 standards. This software runs on Windows environments and you can access it on a 14-day free trial.

2. Auvik (FREE TRIAL)

Auvik Device Mapping

Auvik is a SaaS platform that implements network monitoring and asset management functions through the use of an on-site agent. The central detection service of this package is its network discovery system, which also creates a network asset inventory and draws up a network map.

Key Features:

  • SaaS platform
  • Creates asset inventory
  • Constantly updated

The Auvik network map has a distinctive style. It isn’t a topographical map, so it couldn’t be laid over a world map or an office layout. Instead, it uses a tree structure that identifies the links between network nodes. This is particularly useful if you want to get a switch port summary of one device because you can get a view showing all the ports on the device that are in use, together with a note on the destination of the cable plugged into each of them

The network map gives access to details on each device. These are Layer 2 and Layer 3 systems and you can get details on their addresses, manufacturer, model, and operating capacity. The full Auvik console headlines major issues, which are derived from alerts that identify performance problems or device faults.

There are two plan levels with the Auvik package: Essentials and Performance. The Essentials service offers network device status reports. The Performance deal gives you bandwidth analysis with live capacity reports that can be viewed in the details of each device.


  • Automatic network discovery that is constantly updated
  • A network device inventory
  • Network mapping for Layer 2 and Layer 3 devices
  • Switch port mapping


  • No on-site version

Auvik doesn’t publish its price list. The exact price depends on which plan is chosen and the size of the network that is to be monitored. You can examine Auvik on a 14-day free trial.

Key Features:

  • Maps virtual and physical networks
  • Creates network inventory
  • SNMP-based device monitoring

The OpManager system runs its first system sweep with Ping and the Simple Network Management Protocol (SNMP) to identify every network device and endpoint on the system. It is able to record all information about each device, such as make, model, and operating system.

The network search also reveals how all of the equipment on the system connect together. This information is then made available to a network topology mapping in the monitoring bundle. The system discovery process is continuous, so it adjusts the network inventory whenever changes are made to the network.

The network topology maps are generated anew whenever the map module is accessed by the user. That means that the topology map that is displayed is always based on the latest version of the network inventory and is never out of date.


  • Supports network and server monitoring capabilities built into the topology map
  • Has an option to simulate and track physical connections, great for messy switches and larger complex networks
  • Uses both Ping and SNMP to discover devices, making it more thorough than some smaller tools
  • Maps are automatically redrawn when a device changes, keeping it up to date and accurate every time it is viewed
