Features

Everything IT Needs, Nothing It Doesn't

Stop cobbling together nmap commands. SubnetSweep gives you a fast, clean GUI purpose-built for network discovery.

🔍

Fast Subnet Scanning

Scan /24, /16, or any CIDR range. Concurrent pings, ARP resolution, and hostname lookup run in parallel — a full /24 finishes in seconds.

📡

Device Identification

Automatically identifies manufacturer from MAC address. Instantly tells you if that unknown IP is a Cisco switch, a Synology NAS, or a Raspberry Pi.

FAQ

Common Questions

What does the license cover? ▼
One license covers one workstation. You can deactivate and transfer it to another machine if you replace your computer. The license covers all v1.x updates — no annual renewal required.
How is the license delivered? ▼
Your license key is generated immediately after payment and displayed on the confirmation page. It is also emailed to the address you provide at checkout. Paste the key into SubnetSweep when prompted to activate it.
Does it work without an internet connection? ▼
Yes. Once activated, SubnetSweep runs entirely offline. No internet connection is required for scanning, and no data ever leaves your machine. License verification happens locally.
What Windows versions are supported? ▼
Windows 10 (64-bit) and Windows 11. WebView2 runtime is required — it is pre-installed on Windows 11 and most up-to-date Windows 10 systems. A WebView2 installer is included in the download as a fallback.
Can I use it on multiple machines? ▼
One license covers one workstation. If you need to deploy SubnetSweep across multiple machines, contact us for team or MSP pricing.
What if I need a refund? ▼
We offer a 14-day refund window from the date of purchase. Contact us at [email protected] with your order reference and we will process the refund promptly.
