NetworkLatencyView is a simple tool for Windows that listens to the TCP connections on your system and calculates the network latency (in milliseconds) for every new TCP connection
detected on your system. For every IP address, NetworkLatencyView displays up to 10 network latency values, and their average.
The latency value calculated by NetworkLatencyView is very similar to the result you get from pinging to the same IP address.
NetworkLatencyView also allows you to easily export the latency information to text/csv/tab-delimited/html/xml file, or copy the information to the clipboard and then
paste it to Excel or other application.
- This utility works on any version of Windows, starting from Windows 2000, and up to Windows 8.
Both 32-bit and 64-bit systems are supported.
- In order to capture the TCP packets properly, you have to install one of the following capture drivers:
- You can also try to use the 'Raw Socket' method without installing any capture driver.
However, this method doesn't work in some systems, as well as the latency values detected by using this method are not very accurate.
- When using Network Monitor driver on 64-bit system, you must use the 64-bit version of NetworkLatencyView.
- Version 1.31
- IPv4 addresses on the IP address columns are now sorted numerically.

Start Using NetworkLatencyView
Except of a capture driver that you may need to install, NetworkLatencyView doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - NetworkLatencyView.exe
After running NetworkLatencyView in the first time, the 'Capture Options' window appears on the screen, and you're requested to choose the capture method and the desired network adapter. In the next time that you use NetworkLatencyView, it'll automatically start capturing packets with the capture method and the network adapter that you previously selected. You can always change the 'Capture Options' again by pressing F9.
After choosing the capture method and network adapter, NetworkLatencyView starts to display the latency of every TCP connection initiated on your system.
IP Address Country/City Information
NetworkLatencyView allows you to view country/city information for every destination IP address ('Destination Country' column).
In order to activate this feature, you have to download one of the following external files,
and put the file in the same folder of NetworkLatencyView.exe:
Download the IPv4 CSV file, extract it from the zip/gz file, and put it in the same folder of NetworkLatencyView.exe
- GeoLite City database:
Download the GeoLite City in Binary / gzip (GeoLiteCity.dat.gz) and put it in the same folder of NetworkLatencyView.exe
If you want to get faster loading process, extract the GeoLiteCity.dat from the GeoLiteCity.dat.gz and put it in the same folder of NetworkLatencyView.exe
Integration with IPNetInfo utility
If you want to get more information about the destination IP address displayed in NetworkLatencyView utility,
you can use the Integration with IPNetInfo utility in order to easily view the IP address information loaded directly from WHOIS servers:
- Download and run the latest version of IPNetInfo utility.
- Select the desired connections, and then choose "IPNetInfo - Destination IP" from the File menu (or simply click Ctrl+I).
- IPNetInfo will retrieve the information about destination IP addresses of the selected items.
Translating NetworkLatencyView to other languages
In order to translate NetworkLatencyView to other language, follow the instructions below:
- Run NetworkLatencyView with /savelangfile parameter:
A file named NetworkLatencyView_lng.ini will be created in the folder of NetworkLatencyView utility.
- Open the created language file in Notepad or in any other text editor.
- Translate all string entries to the desired language.
Optionally, you can also add your name and/or a link to your Web site.
(TranslatorName and TranslatorURL values) If you add this information, it'll be
used in the 'About' window.
- After you finish the translation, Run NetworkLatencyView, and all translated
strings will be loaded from the language file.
If you want to run NetworkLatencyView without the translation, simply rename the language file, or move
it to another folder.
