domain-analysis-reporter 0.3.3
Command line utility for analysis domain names and reporting useful information
Requires Python: >=3.10

# Domain Analysis Reporter

The **Domain Analysis Reporter** is a Python script designed to analyze a list of domains and generate detailed reports, including IP resolution, redirection URLs, parent domain, and domain registration information. The output is saved in both Markdown (`.md`) and CSV formats for easy sharing and analysis.

A corresponding CSV file

---

## Features

- Validate domain names using regular expressions.
- Resolve domains to IP addresses.
- Resolve IP addresses to hostnames.
- Follow and capture HTTP redirects for domains.
- Store results in:
  - **Markdown (.md)** for human-readable reports.
  - **CSV (.csv)** for structured data analysis.
- Automatically detects and avoids re-processing previously analyzed domains by loading prior results from CSV.

---

## Prerequisites

Ensure the following are installed on your system:

- **Python 3.6+**
- Required Python packages:
  - `requests`
  - `boilerpy3` - Currently unused


## **Usage**

### **Command-Line Arguments**

| Argument | Description | Required |
| ----- | ----- | ----- |
| `-f`, `--file` | Path to the input file containing domains to analyze. One domain per line. | Yes |
| `-o`, `--output` | Path to the output file (optional). Defaults to the input file name with `_resolved` suffix. | No |
| `-t`, `--time` | Expiration time in days for previous results. Defaults to 30 day. Specifiy 0 to force new analysis. | No |
| `-v`, `--verbose` | Enable verbose mode to display detailed processing information in the console. | No |

---

### **Running the Script**

#### **Example 1: Basic Usage**

```bash
python domain_analysis_reporter.py -f website_domains.txt
```

This processes the domains in `website_domains.txt` and generates:

* `website_domains_resolved.md`
* `website_domains_resolved.csv`

#### **Example 2: Specify Output File**

```bash
domain-analysis-reporter -f website_domains.txt -o custom_output
```

This generates:

* `custom_output_resolved.md`  
* `custom_output_resolved.csv`

#### **Example 3: Verbose Mode**

```bash
domain-analysis-reporter -f website_domains.txt -v
```

This displays detailed processing information in the terminal.

---

## **Input File Format**

The input file should contain one domain per line. Example:

```
example.com
google.com
invalid_domain
```

---

## **Output**

### **Markdown Report (.md)**

A table summarizing the analysis:

| Domain       | Host IPs       | Redirected URL             | Registered Domain | Registrar  | Domain Registration Date  | Domain Expiration Date  | Nameservers  | Timestamp         |
|--------------|----------------|----------------------|------------------------|
| example.com  | 93.184.216.34  | https://example.com     | example-host.com    | NAMECHEAP INC | 2022-11-14 21:49:33 | 2025-01-27 12:35:58 | 2025-11-27 21:49:33 |


### **CSV File (.csv)**

A structured file containing the same data as the Markdown report.

---

## **How It Works**

1. **File Validation**:  
   * Ensures the input file exists and is non-empty.  
2. **Domain Validation**:  
   * Validates domains using a regex pattern.  
3. **Previous Results**:  
   * If a previous `.csv` file exists for the same input, avoids re-processing matching domains.  
4. **Domain Analysis**:  
   * Resolves the domain to an IP address.
   * Captures any redirect URL.
5. **Whois Lookup**:
   * Find the domain registrar
   * Find the domain creation and expiration date
   * Find the domain nameservers
6. **Report Generation**:  
   * Saves the results in both Markdown and CSV formats.

---

## **Error Handling**

* **Invalid Domains**:  
  * Logs invalid domains in the output.  
* **Network Issues**:  
  * Skips domains if unable to resolve or retrieve data within the timeout period.
