Domain/IP Investigation Tool

A comprehensive Domain/IP Investigation Tool built with C++ for Linux/WSL and C# Windows Forms for Windows, allowing users to perform network reconnaissance, DNS lookups, WHOIS queries, traceroutes, and save results in JSON format.

---

Features

Core Functionalities

• Domain and IP resolution
• NSLookup
• Ping test
• WHOIS information
• JSON report generation
• Traceroute (Linux version)
• Service scan (limited)

C++ Version (Linux/WSL)

• Uses system commands: nslookup, ping, whois, traceroute
• Optional colorized output for terminal
• Saves output to report.json
• Robust error handling
• Compatible with WSL / GCC / g++
• Supports both domain names and IP addresses
• Uses libcurl and OpenSSL for network requests

Windows Version (C# Windows Forms)

• Full GUI application with text input and result display
• Requires .NET Framework 4.8 or newer
• JSON output saved as report.json
• Resolves IPs using Dns.GetHostAddresses()
• Runs nslookup, ping, and whois via cmd.exe
• Modern UI layout with scrollable result box
• Fully functional scan button
• Includes error handling and validation

---

Dependencies

Linux C++ Version

• GCC / g++
• libcurl (network requests)
• OpenSSL (-lssl -lcrypto)
• System commands: nslookup, ping, whois, traceroute

Compile:

g++ domain_report.cpp -o domain_report -lcurl -lssl -lcrypto

Run:

./domain_report

---

Windows C# Version

• Visual Studio 2022 (or newer)
• .NET Framework 4.8+
• NuGet Package: Newtonsoft.Json (for JSON handling)

Add Newtonsoft.Json via NuGet:

Install-Package Newtonsoft.Json

Build & Run:

• Open solution in Visual Studio
• Build project
• Run Form1 (main form)
• Enter domain/IP and click Scan
• Results shown in the GUI and saved as report.json

---

Sample Output

JSON Example:

{
  "Target": "dns.google",
  "ResolvedIP": "8.8.8.8",
  "NSLookup": "...nslookup output...",
  "Ping": "...ping output...",
  "Whois": "...whois output...",
  "Timestamp": "2025-12-10 20:00:00"
}

Terminal/GUI Output Example:

TARGET: dns.google
IP: 8.8.8.8

---- NSLOOKUP ----
...
---- WHOIS ----
...
---- PING ----
...

Saved: report.json

Troubleshooting

1. Form1 Not Found (Windows)

   • Ensure file names: Form1.cs and Form1.Designer.cs
   • Class definition: public partial class Form1 : Form
   • All files share the same namespace (e.g., DomainTool)

2. Newtonsoft / JObject Missing

   • Install via NuGet: Install-Package Newtonsoft.Json
   • Add using Newtonsoft.Json.Linq; to your files

3. Linux C++ Warnings

   • Use unique_ptr correctly for popen/pclose
   • Use -Wno-ignored-attributes to suppress template warnings

4. JSON errors / null strings

   • Validate system command output
   • Handle exceptions when converting to string

---

Future Improvements

• Add full traceroute visualization in GUI
• Add DNS records parsing with color-coded output
• Include service scan results in Windows version
• Implement multi-threaded lookups for faster results
• Add custom themes to Windows Forms GUI
