Best IP Scanners for Linux of 2026

OpUtils is an IP address and switch port management tool that engineers can use to efficiently monitor, diagnose and troubleshoot IT resources. OpUtils is a complement to existing management tools, providing real-time monitoring and troubleshooting capabilities. It makes it easy for network engineers to manage their switches and IP addresses. This switch port management tool includes over 20 tools that can be used to monitor network performance, such as monitoring bandwidth usage, monitoring the availability of critical devices, and backing up Cisco configuration files. Advanced IP scanning of IPv4 or IPv6 subnets within your network is possible to identify available and used IP addresses. You can scan all switches in your network, map ports, run port scans, and view details such user, physical location, and more. Block access to rogue devices and identify rogue device intrusions.

Invicti Web + API, previously known as Acunetix, is a DAST solution for discovering, testing, prioritizing, and managing vulnerabilities across web applications and APIs. The platform combines automated runtime scanning with AI-assisted security capabilities intended to bring automated testing closer to the depth of manual penetration testing. It can automatically discover web applications, APIs, shadow assets, unlinked pages, and undocumented endpoints across an organization's attack surface. Invicti detects more than 7,000 security issues, including OWASP Top 10, OWASP API Top 10, and business logic vulnerabilities. Testing capabilities cover single-page and JavaScript-heavy applications, LLM-powered services, authenticated user flows, multi-step application processes, and REST, GraphQL, and SOAP APIs. AI-driven risk scoring analyzes more than 200 signals, while runtime reachability, exploitability, and business context help teams determine which vulnerabilities should receive priority. Proof-based validation is designed to reduce false positives by confirming whether detected vulnerabilities are actually exploitable, with Invicti reporting 99.98% confirmation accuracy for exploitable vulnerabilities. DAST-to-SAST correlation can map vulnerabilities to source code, while AI-powered remediation provides developers with targeted guidance and automated validation retests fixes after remediation. Integrations with CI/CD, ticketing, development, and security systems help organizations incorporate continuous web and API security testing into existing software development workflows.

Angry IP Scanner is an incredibly swift tool designed for scanning IP addresses and their associated ports. It is capable of scanning any range of IPs and operates seamlessly on multiple platforms while being lightweight in design. This tool does not require installation, allowing users to easily copy and utilize it in various environments. The process begins with Angry IP Scanner pinging each IP address to verify its status, after which it can optionally resolve hostnames and identify MAC addresses, among other functions. Furthermore, the data collected about each host can be enhanced through the use of plugins. Additional capabilities include gathering NetBIOS information, such as computer names, workgroup names, and details about currently logged-in Windows users, as well as managing favorite IP address ranges and detecting web servers. Users can also customize openers and save their scanning results in various formats, including CSV, TXT, XML, or as IP-Port lists. Through the provision of plugins, Angry IP Scanner allows for an extensive range of information to be collected about the scanned IPs. This flexibility means that anyone with Java programming skills can develop plugins to further enhance the functionality of Angry IP Scanner, making it a versatile tool for network administrators and tech enthusiasts alike.
