#### Network connectivity checker with advanced features

A powerful bash-based network connectivity testing tool that supports:

Core Testing Features:

* ICMP ping testing with statistics and URL support
* DNS lookup with multiple fallback methods (accepts URLs)
* TCP port connectivity testing with parallel processing
* HTTP/HTTPS status code checking with performance metrics
* SSL/TLS certificate validation with expiry warnings

Network Diagnostics (v1.2.0):

* Show network interfaces with IP addresses (--my-ip)
* Retry failed connections with configurable count and delay
* HTTP status codes with response time and content size
* SSL certificate expiry check with advance warnings

Advanced Features:

* Parallel TCP connection testing (up to 256 concurrent jobs)
* Quick mode parallel processing for wide IP ranges
* Output file support for quick mode results (-o flag)
* IP range support (192.168.1.1-50)
* CIDR notation (10.0.0.0/24)
* Port ranges (8000-8100) and multiple ports (80,443,3306)
* CSV file input for bulk testing
* Multiple output formats (text, JSON, CSV, XML)
* Comprehensive input validation with helpful warnings
* Real-time progress tracking
* Combined reports with dated filenames

Perfect for:

* System administrators monitoring infrastructure
* DevOps engineers validating deployments
* Network diagnostics and troubleshooting
* DNS resolution verification
* ICMP connectivity testing
* HTTP/HTTPS status monitoring
* SSL certificate expiry tracking
* Security auditing and port scanning
* Load balancer health checks

IMPORTANT: For full functionality, run after installation:
sudo snap connect netcheck:network-observe

This connection enables:

* ICMP ping tests (-p/--ping flag)
* Network interface information (--my-ip flag)

Without this connection, features like TCP port tests, DNS lookup, HTTP
status checks, SSL certificate validation, and retry logic work normally.
