## Features

- 🔎 **DNS Lookup** - Query any DNS record type (A, AAAA, MX, TXT, CNAME, NS, SOA, PTR)
- 🌐 **Multi-Resolver Testing** - Test DNS resolution across multiple DNS servers
- ⏱️ **Response Time Analysis** - Measure DNS query response times
- 🔄 **DNS Propagation Check** - Verify DNS propagation across global servers
- 🛡️ **DNSSEC Validation** - Check DNSSEC configuration and validity
- 📊 **DNS Health Check** - Comprehensive domain DNS health analysis
- 🔗 **Reverse DNS Lookup** - Perform PTR record lookups
- 📝 **DNS Record Comparison** - Compare DNS records between servers
- 🚀 **Cache Analysis** - Analyze DNS caching behavior

## Installation

```bash
pip install dns-troubleshoot
```

## Quick Start

### Python API

```python
from dns_troubleshoot import DNSToolkit

# Initialize the toolkit
toolkit = DNSToolkit()

# Perform a simple DNS lookup
result = toolkit.lookup("example.com", "A")
print(result)

# Check DNS propagation
propagation = toolkit.check_propagation("example.com")
print(propagation)

# Run a full health check
health = toolkit.health_check("example.com")
print(health)
```

### Command Line Interface

```bash
# Simple lookup
dns-troubleshoot lookup example.com A

# Check propagation
dns-troubleshoot propagation example.com

# Full health check
dns-troubleshoot health example.com

# Compare DNS across servers
dns-troubleshoot compare example.com --servers 8.8.8.8,1.1.1.1
```
