IP Scanner - Open Port

IP Scanner

An IP scanner is a tool that can give you vulnerable information about your network, it can scan one or more ips and some of them can do it very fast, the vulnerable information can be from what are the open ports in each device, if the device have shared folders, what are the services that the device have and so on.

What IP scanner tool can do for you?

With an IP scanner tool you can easily scan your network to get your network topology and also to check if there are some unwanted or unknown devices connected to your network, this can be archive if you scan your network as in a range of ip address.

There are several software that can one can use to for IP scanner:

  1. Angry IP ScannerQuote from the software publisher:

    Angry IP scanner is fast and friendly network scanner for Windows, Linux, and Mac.

    It is very extensible, allowing it to be used for very wide range of purposes, with the primary goal of being useful to network administrators.

  2. NMAPQuote from the software publisher:

    Nmap (“Network Mapper”) is a free and open source (license) utility for network discovery and security auditing.

    Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.

    Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.

    It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X.

    In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).

  3. Advanced IP ScannerQuote from the software publisher:

    With Advanced IP Scanner, you can scan hundreds of IP addresses simultaneously at high speed. The software scans ports of network computers and finds HTTP, HTTPS, FTP and shared folders. Scan your network (including Wi-Fi network) to get more information about all connected devices including computers’ names and MAC-addresses.

  4. Free IP scannerQuote from the software publisher:

    Free IP scanner is a very fast IP scanner and port scanner. It is intended for both system administrators and general users to monitor and manage their networks.

    Powered with multi-thread scan technology, this program can scan hundreds computers per second. It simply pings each IP address to check if it’s alive, then optionally it is resolving its hostname, scans ports, etc.

So as you can see there are several tools that one can use as an IP scanner tool.

If you are working as a network admin or responsible for devices that connected to the network, it is recommended from time to time to check what are the status of your devices.

It can help you verify that there are no unknown devices that connected in your network, no unwanted ports are open and so on.

IP Scanner for home users:

As home user, if you have a wireless network as most of us have those days, it can be good to use an IP scanner to check that there is no unwanted device connected to you home network, and using your network.

Checking that can be done using one of the above IP scanner tools that I mentioned above.
