CurrPorts
CurrPorts is network monitoring software that displays a list of all presently open TCP/IP and UDP ports on your local computer. For each port in the list, information about the process that opened the port is also presented, including the process name, entire path of the process, version information of the process (product name, file description, and so on), the time the process was formed, and the user who created it.
CurrPorts also allows you to shut undesired TCP connections, stop the process that opened the ports, and export the TCP/UDP port information to an HTML file, an XML file, or a tab-delimited text file. Download
SmartSniff
Your network adapter’s TCP/IP packets may be collected using SmartSniff, and you can examine the captured data as a series of client and server talks. TCP/IP dialogues can be seen in hex dump or ascii mode (for text-based protocols like HTTP, SMTP, POP3, and FTP). (For base non-text protocols, such as DNS). Download
NetworkTrafficView
A network monitoring program called NetworkTrafficView records the packets that travel through your network adapter and shows broad information about your network traffic. The Ethernet Type, IP Protocol, Source/Destination Addresses, and Source/Destination Ports are used to categorize the packet statistics. The following details are shown on each statistics line: Ethernet Type (IPv4, IPv6, ARP), IP Protocol (TCP, UDP, ICMP), Source and Destination Addresses, Source and Destination Ports, Service Name (http, ftp, etc.), Packet Count, Total Packet Size, Total Data Size, Data Speed, Maximum Data Speed, Average Packet Size, First/Last Packet Time, Duration, and process ID/Name (For TCP connections).

Wireless Network Watcher
A simple program called Wireless Network Watcher analyzes your wireless network and shows a list of all the devices and computers that are currently connected to it. The following details are shown for each computer or device that is linked to your network: IP address, MAC address, network card manufacturer, and, if available, machine name. The list of connected devices may also be exported as an HTML, XML, CSV, or text file, or you can copy it to the clipboard and paste it into Excel or another spreadsheet program. Download
IPNetInfo
IPNetInfo is a small utility that allows you to easily find all available information about an IP address: The owner of the IP address, the country/state name, IP addresses range, contact information (address, phone, fax, and email), and more. Download
NetworkLatencyView
A straightforward Windows program called NetworkLatencyView determines the network delay (measured in milliseconds) for each new TCP connection that is found on your computer. NetworkLatencyView shows the average of up to 10 network delay metrics for each IP address. When you ping the same IP address, you get a response extremely comparable to the latency figure produced by NetworkLatencyView. You may also quickly export the latency data from NetworkLatencyView as text, csv, tab-delimited, HTML, or XML files, or copy the data to the clipboard and paste it into Excel or another program.
HTTPNetworkSniffer
HTTPNetworkSniffer is a packet sniffer tool that captures all HTTP requests/responses sent between the Web browser and the Web server and displays them in a simple table. For every HTTP request, the following information is displayed: Host Name, HTTP method (GET, POST, HEAD), URL Path, User Agent, Response Code, Response String, Content Type, Referer, Content Encoding, Transfer Encoding, Server Name, Content Length, Cookie String, and more… You can easily select one or more HTTP information lines, and then export them to text/html/xml/csv file or copy them to the clipboard and then paste them into Excel.
