Best IP Scanners

JDisc Discovery is a comprehensive network inventory and IT asset management solution designed to help organizations gain clear, up-to-date visibility into their IT environment. It automatically scans and maps devices across the network, including servers, workstations, virtual machines, and network hardware, to create a detailed inventory of all connected assets. This includes critical information such as hardware configurations, software installations, patch levels, and relationshipots between devices. One of the standout features of JDisc Discovery is its agentless discovery process, meaning it does not require the installation of any software on individual devices, reducing deployment time and minimizing network impact. It supports a wide range of protocols (e.g., SNMP, SSH, WMI) to gather data, making it compatible with diverse IT environments, whether they are Windows, Linux, or Unix-based.

NetCrunch is commercial, self-hosted, agentless network and IT infrastructure monitoring software for Windows Server. It monitors network devices, servers, virtualization platforms, cloud services, applications, websites, logs, telemetry, and network traffic across on-premises and hybrid IT environments. Network traffic analysis supports NetFlow, sFlow, IPFIX, and other flow technologies. NetCrunch supports 680+ monitoring targets and provides 270+ ready-to-use Monitoring Packs for devices, applications, and operating systems. Licensing is based on monitored nodes and network interfaces rather than individual sensors, checks, or metrics. Real-time dashboards, policy-based monitoring, advanced alerting, and 40+ automated response actions—including remote script execution, service restart, process termination, and device reboot—support centralized monitoring and automated remediation. NetCrunch runs on Windows Server and can monitor infrastructure deployed on-premises, in the cloud, or across hybrid environments.

The vast majority of network scanning software packages require some type of credentialed access to remote devices to detect operating systems. However, using TCP/IP stack fingerprinting and other technologies, Slitheris Network Discovery can identify a wide array of operating systems without credentials or authentication, including Windows (and its Edition), Linux, iOS, and Android. Slitheris can even scan for other details related to the operating system such as Windows Uptime, Cold Boot Time, Time of Day and Domain/Workgroup names, and distinguishes between Domain and Workgroup types, all without needing authentication or credentialed access. This saves the time and frustration trying various usernames and passwords or having to visit PCs and servers in person. Managed Service Providers and other IT Providers will particularly appreciate this unique feature.

Famatech software is used by global leaders in technology, including IBM, Sony, Nokia, HP, Siemens and Samsung, as well as by major telecommunications operators, government organizations, and financial institutions.

SolarWinds® IPAM IP address tracker software automatically discovers your network’s IPv4 addresses and allows you to create IPv6 subnets using a step-by-step wizard. By regularly scanning IP addresses within managed subnets using ICMP, SNMP, and neighborhood scanning, IPAM records and maintains changes in MAC addresses, hostnames, and status (reserved, transient, in use, and available). This automated IP address tracking feature provides this recorded information for any IP address for a specified timeframe. The tracker also includes a timestamp admins can leverage to perform effective network troubleshooting. Accessing detailed device information can help admins quickly analyze and resolve issues. Use SolarWinds IP address tracker to identify current conflicts, see which device had the IP address first, and change the IP of the other device in conflict.

This freeware network scanner displays active computers with logged user names (NetBIOS), MAC and IP addresses. Bopup Scanner also recognizes and shows HTTP (Web) servers running on remote computers (TCP ports 80, 8080), quickly detects online computers, allows to browse shared resources of a remote computer and save results to a text file. Advanced users can enter IP range to scan, change a timeout to resolve a remote host and run the program from a command line interface. Bopup Scanner is a fully portable software. It requires no any setup and installation on a destination computer and can be easily copied to a USB flash drive to move to another PC. The program can be executed with the command line paramaters in order to specify pre-defined options, such as IP range to scan (start and end IP addresses), a path of the file where to save results. So the scanner can be used in batch files as a tool for an automated monitoring.

Netlas.io is a network scanner and search engine on the Internet. Netlas stores DNS records of billions of domain names, hundreds of millions of HTTP responses and SSL certificates. All this information can be obtained through several tools: Responses Search: This collection consists of results from internet scans. Netlas non-intrusive scanners continuously scan internet-accessible hosts and save their responses. DNS Search: These stores domain names, their corresponding IP addresses, and other types of DNS records. IP WHOIS: Information about the owner and management of an IP address, including the IP address range, network provider name, and contact information. Domain WHOIS: Information about the domain owner and registrar, such as contact information, registrar details, registration dates, and expiration dates. Certificates: Database of SSL certificates collected from various sources. Netlas is an indispensable tool for any cybersecurity professional!

Utilize IPAM’s capacity reporting to track subnet utilization and assist with capacity planning. Take advantage of the customizable subnet capacity template for fast, flexible, and centralized reporting. The Subnet Allocation Wizard in IPAM is built to categorize your IP address space into subnets perfectly sized for your network. IPAM’s drag-and-drop interface can create groups containing any number of other groups, supernets, subnets, and individual IP addresses with the added ability to create and use your own custom fields. vRealize Orchestrator (vRO) can be leveraged by vRealize Automation (vRA) and vCenter to automate IP address management tasks. Obtain and reserve unique IP address(es) and release automatically during appropriate machine lifecycle. Using IPAM, you can find abandoned addresses from both static and DHCP systems—just use IPAM’s auto-updated logs to easily identify which addresses have been abandoned and reclaim them.
