Key Features
By scanning whole IP ranges simultaneously, the tool displays all discovered devices in a neat overview. It serves organizations looking for solutions similar to an advanced IP scanner download, while offering deeper network insights. Drill down on individual assets to uncover more device-specific info. An IP scanner like this one focuses on discovering IP addresses and devices, the starting point before you need a broader network scanner that also covers open ports, vulnerabilities, and topology.
Our scanner doesn’t just list IP addresses; it provides in-depth details about each device on your network, including MAC address, manufacturer, device type, Operating System, OS version, model, and more.
This scanner runs on the same lightweight, agentless discovery engine that powers Cyber Asset Intelligence for 30,000+ organizations on the full Lansweeper platform. Whether you’re scanning a small home network or a large corporate environment, it delivers accurate, timely results without slowing your network down.
Tailor your scans to specific needs with flexible settings, allowing you to define IP ranges, scan types, frequency, and include or exclude neighbours for more targeted results, adding capabilities often expected from an advanced IP scanner download.
This free IP scanner download installs as a single, lightweight file for Windows or Mac. There’s nothing else to configure, no drivers and no separate installer, so you can go from download to your first scan in under a minute without entering any credentials.
Port Scanning
Our tool goes beyond abasic local area network scanner by also detecting open ports on each device. Identifying open ports is crucial for network security, because it helps uncover potential vulnerabilities that could be exploited by malicious actors. By scanning for open RDP ports, you can take proactive measures to secure your network, such as closing unnecessary ports and fortifying your defenses against unauthorized access.

Lansweeper’s free IP scanner is a lightweight, credential-free scanning tool that discovers every active device on your network. It detects IP and MAC addresses, device type, and open ports across your subnet without requiring an agent or login credentials. It is a strong, no-cost alternative to a typical advanced IP scanner download, and it shares the same discovery technology used in the full Lansweeper Cyber Asset Intelligence Platform.
Yes. The advanced IP scanner is 100% free to download and use for both personal and business networks, with no trial period, credit card, or hidden limits. It is available for Windows and Mac.
An IP scanner improves network security by surfacing every device connected to your network, including ones IT did not know were there. Unmanaged and unauthorized devices are a common blind spot for both IT and security teams, and 73% of cybersecurity leaders report incidents tied to unknown assets. Scanning regularly helps both teams confirm what is actually on the network before deciding what to secure.
The free IP scanner covers agentless IP discovery and basic device information. Lansweeper is a full Cyber Asset Intelligence Platform trusted by 30,000+ organizations, adding detailed device profiles, vulnerability insights, lifecycle tracking, dashboards, and a report library across IT, OT, and cloud environments. IT and security teams use the full platform to move from simply seeing devices to acting on validated, shared asset data.
Yes. The IP scanner downloads as a lightweight, single executable for both Windows and Mac. No installation of additional software or credentials is required to start a scan, and results appear in a single overview you can drill into device by device.
An IP scanner specifically identifies devices by IP address across a defined range, showing which addresses are active and what is connected to them. A network scanner is a broader term that can include port scanning, vulnerability scanning, and topology mapping. Lansweeper’s free tool covers IP discovery, and the full platform extends into these broader network scanning use cases.
