A network map is a visual map of a network’s physical and virtual connectivity, detailing devices on the network and their inter-relationships, and acts as a schematic guide, playing a vital role in keeping track of network activity as networks grow both in size and complexity over time and across organizations.
Network mapping assists in the breaking down of larger networks into smaller, digestible portions, allowing network administrators to view, track and analyze overall network performance, potential connection errors and identify root causes of issues faster, with more ease and precision.
The network maps are further customizable to suit the needs of network administrators and the detail of information they require.
Here is our list of the nine best network mapping and topology software:

Auto-discovery tools used in network mapping further reduce the time needed to set up network maps and once created, perform network management tasks, as they automatically scan and map the network, discovering all devices connected to the network, indicating the different node relationships and component locations.
This data is then used for a range of purposes, including the drawing up an inventory, topology map detection, flow charts and network diagrams as well as the generation of reports.
With the near constant evolution of networks, particularly in larger IT infrastructure, the roles of auto-discovery tools in automatic scans to update asset information, track changes and updates made to with the aim of ensuring data is available on hand, is fundamental to optimizing services and troubleshooting networks.
These tools allow network administrators to focus on finding solutions to problems arising within networks, saving both time and company resources.
Network mapping also forms an efficient security tool, as it can provide snapshots of live devices connected to wireless and wired networks in real time, speeding up the identification of suspicious connections or IP addresses on the network, with the further option of monitoring or disconnecting them.
Devices turned off can also be pinpointed, providing IP addresses are assigned to the devices, using SNMP, TCP, ICMP amongst others to discover hosts.

Faddom is a software package that is able to discover, document, and map IT assets, which is necessary for ITIL asset management requirements and other tasks, such as application tracking.
The system searches out all devices that run the network, which includes switches, routers, and appliances. It will also identify all endpoints, including desktops and servers. All of those pieces of equipment get written up in an asset inventory. If you change the infrastructure of the network, the tool will spot that alteration on its next sweep of the network and alter the inventory accordingly.
The asset inventory forms the basis of an automated system mapping feature. The network topology map that results from this process also gets automatically updated if anything changes on the network. These updates don’t need to be requested – they are automated and run on a regular basis.
The Faddom system scans will also search through each device and document the firmware or operating system of each. It also scans endpoints for software and creates a software inventory. This can be used as the basis for patch management and license management.
Information in the hardware and software inventories will help you calculate depreciation and plan for replacements. The system will help you implement ITIL standards for IT asset management.
As well as documenting physical infrastructure, Faddom is able to map virtual infrastructure, showing the relationships between virtual servers and virtual machines. The tool can also map a virtual network across the internet, linking sites and reaching out to cloud assets.
Faddom isn’t just useful for network mapping. It is also able to implement application dependency mapping. This is a complicated task that starts with a known system, such as a website, and then identifies calls to other modules. These supporting units might be provided as frameworks, APIs, or plug-ins, and they from for other programs running on servers that could be anywhere and owned by other companies. Those services might also depend on other modules, or microservices, that are provided by other companies.
The application dependency map the Faddom produces will help you monitor the hidden parts of your mobile apps or web applications and then secure them.
Faddom is an asset tracking system that provides network traffic reports, showing the capacity and utilization of each network device and cable stretch.
The dashboard for Faddom shows the network map and each node shown in the plan offers a click-through path to details on the device that it represents.
Faddom runs on a VM, which is proprietary and gets downloaded as part of the software installation process. That means the Faddom software can run on any operating system.
- Simple yet intuitive interface
- Maps networks out through easy-to-read line graphs
- Features automated inventory management
- Can easily visualize network changes over time
- Best for small to mediums sized networks
The pricing for Faddom is based on the number of nodes that you want to monitor, there are two plan levels for the service, called Basic and Standard. You can download a free trial.
