Packet Capture Tool Description

Packet Capture launches a separate app that captures ethernet network packets and stores them in a standard WinPcap packet capture ".cap" file. While not a replacement for a powerful tool like Wireshark, it does give you a quick glimpse into the traffic going through your interfaces without the overhead of a full packet analysis tool. You can view the contents of the packets in the built-in hex viewer or launch an external advanced tool like Wireshark that can read the capture file and provide better decoding of the packets. It is pretty simple to use. After you launch it, press the Capture button. When you are done capturing data, press the Stop button and the display is filled with a list of packets. You can use the built-in simple decoder or launch a more powerful packet analysis tool. Saving the capture or a specific packet is fully supported and you can reload a capture later for future analysis.

Packet Capture Tool Requirements

This application works on Windows 10, 8, 7, Vista, 2012, 2008, XP. We use it with standard ethernet 10/100BaseT network interfaces. Your interface must support 'promiscuous' mode. Wireless 802.11 interfaces usually work if they are supported by Windows. Modems and WAN (PPP/SLIP) interfaces are not supported on Windows 10/8.x/7/Vista due to WinPcap limitations. This feature requires the WinPcap packet driver which we install as part of the NetScanTools Pro package. This Packet Capture Tool supports both IPv4 and IPv6.


  • Captures all packets and provides basic decoding of TCP, UDP, ICMP, IGMP, and ARP packets. Decodes both IPv4 or IPv6.
  • Real time display of the arriving packet count.
  • Time stamping of packet arrival, display of source/destination IPs, protocol type.
  • Parses and shows port numbers, packet length, TTL, TCP sequence numbers and flags.
  • Input Filter by IP address, port number or packet type (ICMP, TCP, UDP)
  • Post-capture display filtering by text found in display.
  • Post-capture searching of the display list of packets for text strings.
  • Post-capture searching of the actual packet contents for text strings.
  • Save the packet capture file separately for future reference.
  • Extraction and export of a single packet to a separate packet capture file (.cap).
  • Load/import a previous session from a saved Packet Viewer capture file.
