Check Port Opened Integrity with Port Checker Tool
Welcome to LutziPortChecker — a powerful utility developed by LutziGoz for scanning ports on specified IP addresses. This tool allows users to identify open and closed ports within a selected range, aiding in network diagnostics, audit tasks, and security assessments. LutziPortChecker supports both local and remote IP scanning and integrates MAC vendor detection for full network profiling.

Introduction to Networking Ports
In networking, a port is a logical communication endpoint. Ports are represented as 16-bit unsigned integers ranging from 0 to 65535. For example, Port 80 is commonly used for HTTP traffic. You can view open connections using tools like "netstat -n".
1. System ports: Range 0–1,023
2. Registered ports: Range 1,024–49,151
3. Dynamic ports: Range 49,152–65,535
LutziPortChecker allows you to scan the following:
- System Ports (0–1023): Used by core services.
- Registered Ports (1024–49151): Available for registration and often used by applications.
- Dynamic Ports (49152–65535): Also known as private or ephemeral ports.
You can select any specific range or scan all ports. Aggressive Mode lets you choose the scan speed: Slow, Medium, or Fast, to adapt to your network conditions.
MAC Vendor Lookup: LutziPortChecker also retrieves the MAC address and performs a vendor lookup, helping identify devices on the network.
Output & Formats
Scan results can be saved in the following formats:
- TXT: Human-readable plain text log
- CSV: Comma-separated format for spreadsheet and data analysis
- DOC: Structured report for formal documentation
Scheduling and Automation
LutziPortChecker includes a scheduling engine that lets you:
- Schedule one-time scans at specific dates and times
- Set recurring scans (e.g., daily, weekly)
- Define retrieval frequency and automate full reports
Scan speed can be customized based on your needs:
- Slow: Safe and stealthy
- Medium: Balanced
- Fast: Aggressive and quick
Below is a visual demonstration of scan speed options.
