Internet Connectivity Test Application - InetConnTest

The InetConnTest application is a versatile tool designed specifically for assessing and troubleshooting internet connectivity on Android devices. Whether you're a developer debugging network-related issues or an end-user trying to diagnose connectivity problems, this app provides a comprehensive suite of tools to help you understand your device's network status.

At its core, InetConnTest offers users a straightforward way to monitor their current network connection status. The "CONNECTION STATUS" feature displays essential details about both mobile and Wi-Fi connections, giving you real-time insights into signal strength, network type, and connection quality. This section serves as a quick reference point for understanding whether your device is connected to the internet and how stable the connection is.

One of the standout features of the app is the HTTP CONNECTION TEST. By sending a test message to an HTTP/HTTPS server, this tool allows you to verify the functionality of your network connection. The response from the server is displayed as raw data, providing clear feedback on whether the connection is successful. If your device uses a proxy for network access, the test will route the request through the configured proxy, helping you identify potential issues with proxy settings.

For more advanced users, the TCP CONNECTION TEST offers a deeper level of analysis. This feature enables you to establish a direct TCP connection to a specified server and port. Once the connection is confirmed, the app sends predefined data strings to the server and displays any responses received. Unlike the HTTP test, TCP requests bypass proxies entirely, making it ideal for diagnosing issues related to proxy configurations. Additionally, since the TCP port can be customized, this tool is particularly useful for testing non-standard services like IMAP email (port 143) or FTP (port 21).

Another valuable feature is the NAT CHECK, which helps determine your public IP address when accessing the internet. The app simultaneously displays both your local and public IP addresses, using a STUN server to retrieve the latter. This information is crucial for identifying whether your device is behind a NAT firewall and can assist in resolving issues related to restricted network access.

The INFO menu complements these technical features by offering practical advice and troubleshooting tips. If you encounter connectivity problems, this section provides step-by-step guidance on what to check and how to resolve common issues.
