Angry IP scanner is a very fast IP scanner and port scanner. It can scan IP addresses in any range as well as any their ports. Its binary file size is very small compared to other IP or port scanners. Angry IP scanner simply pings each IP address to check if it's alive, then optionally it is resolving its hostname, determines the MAC address, scans ports, etc. The amount of gathered data about each host can be extended with the available plugins.



Free Port Scanner is a small, fast, easy-to-use and robust port scanner for the Win32 platform. You can scan ports on fast machines in a few seconds and can perform scan on predefined port ranges. This tool uses TCP packets to determine available hosts and open ports, service associated with port and other important characteristics.  The tool is designed with a user-friendly interface and is easy to use.

Sam Spade is a free and useful network query utility.Here are some key features of "Sam Spade":

Each tool displays it's output in it's own window, and everything is multi-threaded so you don't need to wait for one query to complete before starting the next one

Some functions are threaded still further to allow lazy reverse DNS lookups (never do a traceroute -n again)

The output from each query is hotlinked, so you can right click on an email address, IP address, hostname or internic tag to run another query on it

Appending the results of a query to the log window is a single button function

There's a lot of online help, in both WinHelp and HTMLHelp formats. This includes tutorials, background information and links to online resources as well as the program manual itself.

TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.
