The Angry IP scanner scans IP addresses and ports very quickly. It can scan IP addresses from any range and any ports. It is lightweight and cross-platform. It doesn't require installation and can be copied and used wherever you like. Angry IP scanner simply pings each IP to verify that it is alive. If it is, it will resolve its hostname, determine the MAC address, scan ports, and so on. Plugins allow you to increase the amount of data collected about each host. You can also access additional features like NetBIOS information (computer, workgroup, currently logged-in Windows user), favorite address ranges, webserver detection, customizable openers, and NetBIOS information (computer, workgroup, and currently logged in Windows user). You can save scan results to CSV, TXT or XML files. Angry IP scanner can collect any information about scanned IPs using plugins. Anyone who can code Java code can create plugins and extend the functionality of Angry IP scanner.

Network Scanner is an IP scanner. It can scan large corporate networks with hundreds of thousands of computers as well as small home networks with many computers. The program can scan a variety of IP addresses, computers, and ranges of addresses. However, the number and subnets that it can scan is unlimited. Network Scanner will display all shared resources, including hidden NetBIOS (Samba), shared resources as well as FTP and web resources. Network Scanner is available to both network administrators as well as regular users. It can be used to audit network computers and search for available resources. Network Scanner can not only locate network computers and shared resources but also check access rights. Users can mount the network drive, or open them in Explorer. The program allows you to easily export the network scan results to an XML or HTML file, or save them in the program.

This freeware network scanner displays active computers and logs user names (NetBIOS), IP addresses, and MAC addresses. Bopup Scanner can also identify and show HTTP (Web) servers on remote computers (TCP port 80, 8080). It quickly detects online computers and allows you to browse shared resources and save the results to a text file. Advanced users can enter IP ranges to scan, modify a timeout to resolve remote hosts, and run the program via a command-line interface. Bopup scanner is portable. It does not require any setup or installation on a destination PC. The program can also be copied to a USB flash disk to be transferred to another computer. You can run the program with the command line parameters. This allows you to specify predefined options such as IP range (start and end IP addresses), path to the file, and where to save results. The scanner can also be used in batch files to automate monitoring.

You can get the information you need with minimal setup. IP Scanner, a cloud tool, scans your network and returns a list of devices it finds. You can filter, search, and export devices to CSV. It will scan a local subnet by default. However, you can define your own IP range. The IP Scanner lists every device's hostname and IP address, as well as its vendor, OS, MAC addresses, description, open ports, and whether it's up/down. The type of device being scanned will determine the type of data that is returned.

A free IP scanner is a fast IP scanner and port scanner. It can be used by system administrators as well as general users to monitor and manage networks. This program is powered by multi-thread scanning technology and can scan hundreds of computers per second. It simply pings each address to verify that it is alive. If it is, it can optionally resolve its hostname, scan ports, and so on. A free IP scanner can display NetBIOS information, including the host name, workgroup, current logged user, and MAC addresses. The information can be exported as plain text files. Administrators will appreciate the fact that the Free IP Scanner scans hundreds of computers per second. It can be configured to scan at different priority levels, limit the number of threads, and so forth. To enter the first and last IP addresses, you can use two fields in IP Range. You can enter a lower number than the first IP address. It is okay to translate your input.
