DisNet is a Go-based network discovery and port-scanning utility. It performs optional host discovery for a CIDR range and then scans a selected host (or a provided host/domain) for open TCP ports.

Features

• CIDR-based host discovery with selectable target
• Direct scanning for a single host or domain
• Concurrent TCP port scanning with a configurable range
• Common service name mapping for well-known ports
• Private/public IP classification

Requirements

• Go 1.20+ (or a compatible version)
• Administrator privileges (required by the current implementation)

Install

Clone the repository and build:

1. git clone <repo-url>
2. cd DisNet
3. go build -o disnet

Usage

Run the executable and follow the prompts:

1. Enter a CIDR block, host, or domain (e.g., 192.168.0.0/24 or example.com).
2. Enter a port range (e.g., 20-80) or a single port.

Examples:

• Scan a CIDR network, then select a discovered host: 192.168.0.0/24
• Scan a single host: 192.168.1.10
• Scan a domain: example.com

Notes

• Host discovery uses ping with Windows-style flags. On non-Windows systems, adjust the command if needed.
• Port scanning is TCP-based and uses a 1-second timeout per port by default.

Roadmap

• Configurable timeouts and concurrency
• Optional UDP scanning
• Structured output (JSON/CSV)
