How to Purchase CommView for WiFi

Latest IP Connections

This tab is used for displaying detailed information about WLAN connections (IP and IPv6 protocols only). To start capturing packets, select File = > Start Capture in the menu, or click on the corresponding button on the toolbar. Please note that this tab will not be populated unless the program is capable of decrypting WEP/WPA-encrypted WLAN traffic. If your WLAN uses WEP or WPA encryption, all the data packets being sent are encrypted, and it is impossible to obtain information about their IP address unless you have entered the correct decryption key by clicking Settings => WEP/WPA Keys in the menu. Additional steps are required in case of WPA decryption; see Understanding WPA Decryption.

The meaning of the table columns is explained below:

Source IP, Destination IP – shows the pair of IP addresses between which the packets are being sent. The program automatically determines the location of any IP address, and depending on your geolocation settings, may show the country name or flag next to the IP address. For more information, see Setting Options.

In – shows the number of packets received.

Out – shows the number of packets sent.

Sessions – shows the number of established TCP/IP sessions. If no TCP connections were established (connections failed, or the protocol is UDP/IP or ICMP/IP), this value is zero.  

Ports – lists the remote computer's ports used during the TCP/IP connection or connection attempt. This list can be empty if the protocol is not TCP/IP. Ports can be displayed either as numeric values or as the corresponding service names. For more information, see Setting Options.

Hostname – shows the remote computer's hostname. If the hostname cannot be resolved, this column is empty.

Bytes – shows the number of bytes transmitted during the session. 

Last packet – shows the time of the last packet sent/received during the session. 

You can show or hide individual columns by right-clicking on list header or using the View => Latest IP Connections Columns menu. The column order can be changed by dragging the column header to a new location. Right-clicking on the Latest IP Connections list brings up a menu with the following commands:

Quick Filter – finds the packets sent between the selected IP addresses and displays them in a new window. The same action is performed when you double-click on this window.

Copy – copies the local IP address, remote IP address, or hostname to the clipboard.

Show All Ports – displays a window with the complete list of ports used in communicating between the selected pair of IP addresses. This is useful when many ports were used, and they do not fit into the corresponding column.

Data Transfer – displays a window with information on the data transfer volume between the selected pair of IP addresses and the time of the last packet.

Jump To – allows you to jump to the first/last packet with the selected source/destination IP address; the program will display the Packets tab and set the mouse cursor to the packet that matches the criterion. 

SmartWhois – sends the selected source or destination IP address to SmartWhois, if it is installed on your system. SmartWhois is a stand-alone application developed by our company, capable of obtaining information about any IP address or hostname in the world. It automatically provides information associated with an IP address, such as domain, network name, country, state or province, city. The program can be downloaded from our site.

Create Alias – brings up a window where you can assign an easy-to-remember alias to the selected IP address.

Save Latest IP Connections As – allows you to save the contents of the Latest IP Connections tab as an HTML report.

Clear Latest IP Connections – clears the table.

More Statistics – shows a window with data transfer and protocol distribution statistics.
