IT will spot any changes in your network and automatically update its network inventory. The service also draws up a series of network visualizations, based on the inventory. This is a live service, so any changes detected by the discovery module are instantly reflected in the network topology maps.

The network maps are interactive and you can query each node for statuses by hovering your pointer over it, or click through to a detailed status screen.

Datadog Network Monitoring

Price: Datadog Network Performance Monitor is a subscription service, priced at a rate per host of $5 per month when paid annually or $7.20 month to month.

3. ManageEngine OpManager – FREE TRIAL

ManageEngine OpManager has an automatic network mapping utility built into its network monitoring capabilities. As well as monitoring networks, this system monitors servers and some applications and services. Among the services that this monitor will supervise are virtualizations and it maps the virtual infrastructure as well.

The mapper in OpManager creates network topology maps on demand. The information that these maps are based on comes from the network inventory. That inventory is constantly updated with periodic network scans. That means the topology map that you see is always based on the latest version of the network.

The topology mapper is able to present the network in a number of different formats. Here is an example of a layer 2 map, which only shows the switches on the network.

ManageEngine OpManager

There are other layouts available. The service can plot a WAN on top of a real world map. It can show a 3D image of the office building or a floor plan with the network and all connected equipment shown. It is also able to present a rack view.

Lucidchart has a great offering and as of lately, probably one of the top solutions for those looking to create quick and easy topology diagrams of their network infrastructure.

They have a wide array of pre-built templates that are ready for you to plug in your data and quickly modify to your needs.

Some examples of pre-built templates include the following in this image:

As you can see, you can grab an existing diagram and not have to waste time configuring and building one from scratch that will likely take twice as long to get to the same starting point as one of these.

Lucidchart has a great pricing program in place that allows for flexibility of use and allows you to quickly scale to more users if needed on the fly.

As of this writing, here is the pricing structure for Lucidchart for Network diagramming:

One of the most intersting and exciting features that stood out to us when looking at lucidchart was the fact that you could import and export Visio file format directly into Lucidchart and back out if needed.

This gives you the flexiblity to share diagrams with people who are still using Visio for their diagramming needs.

8. eDraw

eDraw Software

eDraw MAX definitely has the feel of Microsoft Visio and ConceptDraw Pro, with its elegant appearance and ease of use, it reminds us of using Microsoft Word, as the menu bar and ribbon is very similar to it.

This software package is more of an All-in-One business diagram software, which allows users to not only map out LAN’s and WAN’s, but produce compelling organizational and flow charts, business presentations, building plans, web design layouts and many more.

eDraw is vector-based, which means you can Zoom in as close as you want without distorting any of the objects and elements on the page, and models can scale up if needed to print in large formats easily, and more importantly, print with clear, defined lines that are not distorted from resolution issues.

This software package also has the feature to import Visio xml files and change as needed, giving you up to 2000 types of clip art bundled into the installation.

Price: Free Trial and $99 Full Edition.

9. LanFlow

LanFlow Topology Mapping

Lanflow is a tool that is specifically meant for diagramming networks and computer related schematics primarily, unlike some of the previous software we discussed, that are more well-rounded in terms of flexibility and functionality (business diagramming).

LanFlow is has a drag-n-drop interface with allows you to place network equipment onto the canvas and then use “connectors” to interconnect them all.

They give you the flexibility of defining borders and line weights as well. Some of the other features this software has to offer are hundreds of share and symbols, in both black & white and 3D, Vector based designs, Snap Grid functionality for easy alignment of items, flow symbols and jogs (also known as a crossover) and much much more.

This software is fully featured and specifically designed for network mapping schematics.

Price: $99 for Single license and discounts available for multiple license purchases.

10. Network Notepad (Free)

Network Notepad Diagramming Software

Network Notepad (FREE) is just as the name of the software implies, a program for creating interactive diagrams of networks and their components.

This tool has a great add-on worth mentioned called “CDP Neighbor Tool” (Cisco Discovery Protocol), which is basically a function that will pull information from the CDP table of a selected Cisco device that has CDP enabled and draw and map out the network components based on that table.

Fully scalable using vector based graphics, zooming in and working on a granular level is a pleasure with no pixelated resolution and has the ability to create “Custom Shapes” for your devices within the software.

The interface of the software feels like Microsoft Word 2003 interface, with no ribbon menu as some of the other software we have reviewed.

The FREE edition runs on Microsoft Windows 9x, NT, 2K, XP, Vista, with no mention of Windows 7, 8.1 or 10.

The Professional version does however run on all the newer Microsoft versions, including Windows 10, 8, 7, Vista, XP and 2000. Just something to keep in mind when downloading it.

Price: Free version and Professional Version at £16 GBP per license.

11. Microsoft Visio

Microsoft Visio Diagraming LAN/WAN Network

Microsoft Visio is probably the most well known network mapping and layout software among Business & IT professionals alike.

As you can imagine, the price of the Software justifies its position among the others, starting at $299 and going up to $590 for Pro Version, its no wonder that many of the software packages we reviewed above have built their interfaces around Microsoft popular Ribbon and Menu systems.

The newer versions of Visio now have added functionality that allows people to comment on your Diagrams through either Visio itself or through a Browser (using Sharepoint) and even goes as far as built in Instant messaging using either Microsoft Skype for Business or Lync.

Bundled into the software are over 70 pre-built templates and thousands of Shapes, including IT focused elements that represent Active Directory components, as well as detailed network components and Network appliances and routes.

Visio also has shapes and components for Data center, help desk, HVAC layouts, Enterprise and Home network diagramming and many more options.

Its truly a fully featured diagramming tool for not only business professionals, but for IT professionals who need serious diagramming capabilities.

One downside to Visio is the inability to scan Networks and automatically populate your diagram for you natively, although you can do this with an add-on for Microsoft Baseline Security Analyzer called Visio Connector, which can be used to scan your network and view the results in a fairly thorough Visio diagram.

Price: Visio Standard = $299. Visio Professional = $589. Visio Pro for Office 365 = $15/month

Conclusion

We've reviewed all the aforementioned Network Mapping Software packages listed above and Highly Recommended you do the same, as each software has its pro's and con's and Extensive list of Features and Functionality.

If you need a piece of software that will automatically map out Network Diagrams for you and keep it up-to-date, then try one of the software packages from above.
