IPPort

IPPort is a lightweight batch utility script (Batch/CMD) designed to automate essential point-to-point connectivity tests between the local machine and a target host (IP or URL). It combines the efficiency of the native Batch ecosystem with dynamic PowerShell graphical interfaces, making rapid network troubleshooting agile and accessible for technicians and administrators.

🚀 Features

• Guided Graphical Interface: Utilizes graphical input boxes (InputBox) and message boxes (MessageBox) via PowerShell, eliminating the need for the operator to type parameters directly into the command line.
• Dynamic Internationalization (Bilingual): Automatically detects the default Operating System language (by querying the LocaleName key in the Windows Registry) and dynamically adapts the entire interface and messages to either Portuguese (PT) or English (EN).
• Preventive Host Filtering: Features a security validation that blocks script execution if the operator enters potentially malicious, spam, or incompatible domains (such as .onion and .xyz extensions).
• Dynamic User-Agent: Generates a unique random identifier (IPPort_XXXX) on every execution. This signature is injected into the curl HTTP requests, mitigating automated blocks by WAFs (Web Application Firewalls) during server health checks.
• IPv6 Support: Structured to accept IPv6 addresses, guiding the user to enclose them in brackets (e.g., [XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX]).

🔍 Execution Sequence (Diagnostic Pipeline)

The script performs a direct sequential sweep to isolate network failures clearly:

1. TCP Connectivity Validation (Test-NetConnection): Tests connection to a specific port (if provided) or runs a default port diagnostic, retrieving technical details about the connection interface.
2. Simple Ping (ping): Validates basic ICMP echo responses and route latency.
3. DNS Resolution (nslookup): Queries default name resolution to verify if the domain correctly resolves to a valid IP address.
4. Canonical Address Lookup (nslookup -type=CNAME): Identifies the existence of aliases or redirects within the target's DNS infrastructure.
5. HTTP Header Inspection (curl): Executes an HTTP HEAD (-I) request with a maximum timeout of 120 seconds, applying the dynamic User-Agent to analyze HTTP return codes (e.g., 200 OK, 403 Forbidden, 500 Error).
6. Route Tracing (tracert): Lists all hops the packet traverses until reaching the destination, ideal for identifying bottlenecks or routing loops.

📋 Prerequisites

• Operating System: Windows 10 or Windows 11.
• Native Dependencies: The script utilizes native Windows components (powershell.exe, curl.exe, standard networking tools). No third-party installations are required.
• Privileges: Can be executed with standard user privileges.

🛠️ How to Use

1. Copy the original IPPort script code.
2. Open Notepad or your preferred text editor.
3. Paste the code and save the file with a .bat or .cmd extension (Example: IPPort.bat).
4. Encoding Tip: Ensure you save the file with UTF-8 encoding to guarantee that special characters and accents render perfectly within the terminal's code page (chcp 65001).
5. Double-click the generated file to start the tests.
6. Or just download it and run.
