01
Start a project Start from the beginning. Maintain control over the network.
Plan the network basics, visualize it, control the addresses and devices, and verify the configuration. It is a full lifecycle in one project.
The first easy network-engineering project workspace
Design the network. Keep the project together.
Workspace for network engineers to design, build, validate, and document network projects. Powered by AI that has your back.
Built by computer network administrators for the work that happens before, during, and after a change window.
01
One project
The network basics, devices, addressing and output stay connected.
07
Vendor platforms
The same intent translated into each platform's own syntax.
∞
Full lifecycle
Design, build, validate and document from one workspace.
One plan, seven platforms
The same intent, in each platform's own syntax
NetField is your trusted network configuration generator. Input the data and get full configuration output for any platform. This example covers 10.20.0.0/16 and 1,786 usable addresses.

write memoryEach platform is a translation, not a template substitution. The intent is shared; the syntax is not.
Switch platforms without rebuilding the plan. Keep the engineering decision and change the output.
From first address to final document
Start from the beginning. Maintain control over the network.
NetField allows you to plan the network basics, visualize it, control the addresses and devices, and verify the configuration. It is a full lifecycle.
02
Explore the planner Configure the segments. If needed, when needed.
Generate every part of the configuration so you always have a full picture at the end. Keep the intent, even when the syntax changes.
03
Validate a config Verify your work. Make it correct.
If you already have a running configuration, validate it before entering any data into NetField. It is important that the network works.
04
See the workspace Just send the project details as soon as finished.
Generate documentation from every aspect of your network directly in NetField. The final document has a consistent standard and the information others need.
Verify your work. Make it correct.
Find the problem before it becomes the incident.
If you already have a running configuration, validate it before entering any data into NetField. It is important that the network works.
errormissing-vlan
VLAN 10 is used but never declared
Referenced by Vlan10 but there is no "vlan 10" statement. On most platforms the VLAN will not be created and traffic will be dropped.
errorduplicate-ip
Duplicate IP address 10.0.10.1
Configured on both Vlan10 (line 1) and Vlan20. One of the two interfaces will fail to come up.
erroroverlapping-subnets
Overlapping subnets on different interfaces
Vlan10 (10.0.10.0/24) overlaps Vlan20 (10.0.10.0/24). Routing between them is ambiguous.
Real output from the NetField validator, with deliberate faults to review.
Coming to the workspace
Streamline the workflow with AI.
In developmentLet the NetField AI be your network engineer. With the entire project as context.
The workspace is designed so AI can work from the same addressing plan, devices, topology and generated configuration you already understand.
Free tools for the work between projects
Explore and use our free network tools.
Useful on their own, even better when they become part of a project. Start with the reference tools you need today.
Calculate
Addressing and network calculators
Work through subnetting, IPv4 and IPv6, link budgets, power and more with tools built for the job.
Reference
Vendor command library
Find the syntax, examples and common misreadings that keep a small configuration detail from becoming a long troubleshooting session.
Reuse
Config templates
Start from repeatable device baselines with typed placeholders, then adapt them to the project in front of you.
Made for the whole network team
NetField is made for everyone.
Different roles, same need: a clear network project that keeps the details together and makes the next decision easier.
Freelance consultants
Turn a brief into a reviewable network project without stitching together a new toolchain every time.
Students and learners
Learn the reasoning behind the plan, then see how the same intent becomes real vendor syntax.
In-house network teams
Keep addressing, devices, configuration and documentation together so the project stays understandable.
System integrators
Create repeatable project foundations without pretending every platform works the same way.
Senior network engineers
Automate deterministic work and keep your attention on the decisions that still need experience.
Your network project, in one place
Build the network. Send the project details.
Start with the basics, keep control of the details, and finish with a configuration and document you can review.
