Understanding Network Diagrams and Network Maps
Network diagram and network map are interchangeable terms for a visual tool that illustrates the connections between components within a network. These components, known as nodes, include devices like routers, hubs, and firewalls. Think of it as a blueprint of your IT infrastructure.
Network mapping provides valuable insights into your network:
- Device Inventory: Clearly identifies all devices present on your network.
- Data Flow Visualization: Shows how data travels between devices.
- System Update Planning: Helps in strategizing and implementing system updates effectively.
- Performance Issue Detection: Aids in identifying, diagnosing, and reporting network performance bottlenecks.
Network maps can focus on two primary aspects:
- Physical Networks: Depict the physical infrastructure, including cables, wiring, and physical connections.
- Logical Networks: Illustrate the flow of data, encompassing elements like subnets, firewalls, and network segments.
Some diagrams combine both physical and logical aspects, offering a comprehensive view. Other specialized network diagrams, such as switch diagrams, computer network diagrams, and network security diagrams, highlight specific facets of your network for focused analysis.
Why Your Business Needs a Network Diagram
Creating, maintaining, and utilizing network diagrams is not just good practice; it’s essential for any organization that relies on a network infrastructure. A network diagram provides critical visibility into how network components interact and the overall health of your network at any given moment.
Investing in a network diagram creator offers benefits that extend far beyond simple visualization. These tools are instrumental in:
- Planning New Network Structures: Designing the architecture of a network from the ground up.
- Updating Existing Network Layouts: Adapting diagrams to reflect changes and expansions in your network.
- Proposing Infrastructure Modifications: Visualizing and planning infrastructure upgrades or changes.
- Troubleshooting Network Issues: Pinpointing and resolving network problems quickly and efficiently.
- Ensuring Regulatory Compliance: Maintaining a network structure that adheres to industry and legal requirements.
- Tracking Network Component Inventory: Keeping a record of both legacy and newly added network devices.
- Facilitating Communication and Collaboration: Providing a shared visual understanding of the network for team members and stakeholders.
Depending on the network diagram generator you choose, you can achieve anything from a basic network overview to a highly detailed network schematic. This article highlights network map creators offering varying degrees of creation, customization, and troubleshooting capabilities to suit diverse needs. As mentioned earlier, SolarWinds NTM consistently ranks as a top network mapper due to its extensive features and intuitive interface.
Streamlining Network Diagram Creation
While manual network diagram creation is theoretically possible, utilizing a dedicated network diagram and map creator is the most efficient and effective approach. This software is designed to automatically generate network maps by scanning your network, saving valuable time and resources. Manual diagram creation is often complex, time-consuming, and prone to errors, even for experienced IT professionals. A small mistake can lead to significant complications later on. Investing in a network map creator ensures accuracy, clarity, and easy sharing of your network diagrams.
The best network diagram generators combine automated scanning with customization options. These tools not only automatically map your network but also allow you to personalize node icons, rearrange elements within the map, and maintain up-to-date diagrams with real-time node status monitoring. This combination of automation and flexibility is key to efficient network management.
Exploring the Top 7 Network Diagram Creator Scanning Tools
Here’s a detailed look at seven of the best network diagram creators available, focusing on their scanning capabilities and overall features:
1. SolarWinds Network Topology Mapper (NTM)
SolarWinds Network Topology Mapper excels in network diagram creation by offering comprehensive mapping from multiple perspectives. Its standout feature is the ability to automatically generate multiple diagrams from a single network scan. NTM simplifies sharing diagrams in various formats, including Microsoft Visio, PDF, and PNG.
Flexibility is another key advantage. NTM allows for easy modification of network devices on the diagram, offering both automatic adjustments and manual editing options. Furthermore, you can schedule periodic network re-scans to ensure your network maps are always current. Experience the power of automated network mapping with a 14-day free trial of SolarWinds Network Topology Mapper.

2. InterMapper (HelpSystems)
InterMapper by HelpSystems, similar to NTM, is a robust all-in-one network map generator. It excels at real-time discovery and mapping of devices on both physical and logical networks. InterMapper offers extensive customization, allowing you to tailor maps, topologies, and color schemes, even animating node icons for enhanced visual clarity. Pricing is device-based, scaling with your network size. Explore its capabilities with a 30-day free trial.
3. Lucidchart
Lucidchart is a versatile diagramming tool ideal for creating various diagrams beyond network maps, including flowcharts and UML diagrams. It shares NTM’s advantage of seamless integration with other applications and automatic data backup. However, Lucidchart lacks auto-discovery features, meaning it doesn’t offer the same level of automated network mapping and maintenance as other tools on this list. A free single-user version and various professional tiers are available.
4. LanFlow
LanFlow is a strong choice if you prioritize ease of use and design flexibility in a network diagram builder. It provides a range of helpful design tools, including pre-defined templates and custom diagram creation, an optional snap grid for precise alignment, dynamic figure and flow labels, hyperlink and website integration, and full zoom capabilities. Test out LanFlow with a 30-day free trial.
5. Microsoft Visio
Microsoft Visio is an industry-standard diagramming tool known for its reliability and seamless integration within the Microsoft ecosystem. Visio offers semi-customizable features with pre-loaded templates and themes for network visualization. It also provides data protection features like loss prevention and Information Rights Management (IRM). However, like Lucidchart, Visio does not automatically generate network diagrams from network scans, requiring manual input. Both Standard and Pro versions are available, with a 30-day free trial.
6. ConceptDraw DIAGRAM
ConceptDraw DIAGRAM, formerly ConceptDraw PRO, is primarily designed for network diagram creation. Features like Smart Connector and Building Plan Designer aim to automate the diagramming process. ConceptDraw DIAGRAM also allows for custom node icon creation. While its interface might appear somewhat dated, it remains user-friendly and easy to learn. A 21-day free trial is offered.
7. SmartDraw
SmartDraw is a web-based network diagram maker, offering accessibility from any location with an internet connection. While customization is limited, SmartDraw’s ease of data input and professional output make it a good option, particularly for smaller businesses. However, its per-user pricing model can become less cost-effective for larger organizations. A free online version is accessible here.
