10 Best IP Scanners in 2024 (Free & paid)

Looking for the best IP scanner software out there? Here is a list of the top 10 scanners and how you can benefit from them.

IP scanners check computer ports to see which ones are live and which ones are potentially vulnerable. The law here is simple: If you don’t fix your system’s weak points, then a hacker might exploit it.

Ports enable communication between two or more computers, so they are important. But the different applications that run these services often have bugs that anyone can exploit.

By using network analysis tools, you can keep your home or company computers safe, so they can continue to serve you well.

Here is a list of the top 10 and best IP scanners out there. Knowing them is important because good computer security can save you a fortune.

The software provides information on all available IP addresses in the range. And these include open ports, listening services, domain names, and ping times.

You can also use it to scan specific hosts or to gather NetBIOS information. Plus it is extensible with plugins. So, any Java coder can improve on the source code.

Being a Java program also means that the scanner needs no installation to run. Angry IP Scanner has seen over 29 million worldwide downloads.

You can also connect to the other computers using Radmin and this allows you more interaction with the machine, including switching it off remotely.

For downsides, Advanced IP Scanner does not offer port scanning or other network analysis features. But it is a great tool if you just want to keep an eye on a simple network. And it counts over 60 million downloads.

Created by Gordon Lyon, Nmap is an impressive free and open-source network scanner. It started life on Linux systems but has also become available on Windows and macOS systems.

Nmap scans ports, identifies the hosts on a network, plus DNS and MAC addresses. It also identifies the versions of running services, as well as their operating systems and even the hardware.

You can use it for practically any network application, from auditing to network inventory, mapping, management, finding vulnerabilities to exploit, sub-domain search, and DNS queries. It can handle enterprise-scale networks, as well as smaller ones.

The original Nmap is a command-line tool, so it might not be for everyone. But Zenmap provides a graphical user interface, which makes it easier for beginners to use. Other interfaces include NmapFE and the IVRE web interface.

If you plan on administering a network for the long term, then Nmap is one tool you should know. The other two are listed below.

After Nmap, Wireshark is another package that comes pre-installed in Kali Linux, the hacker’s OS of choice. It is an impressive packet sniffer and can be quite helpful for investigations.

While hackers use Wireshark to spy, a network admin can use it to analyze problems or conduct security checks. You can even use it to identify malware and to find out who it is communicating with.

Wireshark works by capturing data packets from Ethernet, WiFi, and Bluetooth communications. It then analyzes the data and provides relevant information, such as the number of packets, time, source, destination, protocol, length, and extras.

You can use Wireshark for much more stuff when you get to know its features, filters, and capability to sniff data from larger networks. Downloads are available for Linux, Windows, and macOS.

Highlights: Powerful software

Cons: Not a typical IP scanner

10. Metasploit

The best way to prevent hackers from exploiting your system is to try hacking yourself first. And Metasploit is the perfect tool for that.

After you have identified basic information about a network, including OS and server versions, hardware, and so on. The next step is to consider available exploits for that configuration, and that’s what the platform helps you to achieve.

Metasploit is an open-source project, but there is also a paid Metasploit Pro version with a free trial. It comes pre-installed in Kali Linux and is available for Windows and macOS systems as well. Its free version also includes Zenmap, the GUI-based Nmap application.

The package includes hundreds of exploits and payloads for you to try out. But you are still free to create custom code if you know what you are doing.

Highlights: Popular pen-testing solution, simplifies hacking

Cons: Learning curve
