Simple Process

How PortScan6 Works

Our straightforward 3-step process makes IPv6 port scanning quick and effective.

1

Enter IPv6 Address

Input any IPv6 address or range using CIDR notation. Our intelligent system validates all inputs and can even scan from hostname to IPv6 address resolution. You can also enter multiple addresses for batch scanning of your entire network infrastructure.

2

Configure Scan Parameters

Choose which ports to scan or select from predefined groups like “Web Services” or “Database Ports”. Adjust scan intensity and customize detection methods for your specific needs. Set advanced options for deeper analysis or keep it simple with default settings for quick scans.

3

Analyze Comprehensive Results

Review detailed findings including open ports, detected services, response times, and security recommendations. Export results in various formats or use our visualization tools to understand your network topology at a glance. Save scan configurations for repeated security audits over time.

Questions & Answers

Frequently Asked Questions

Find answers to the most common questions about our IPv6 Port Checker.

What exactly is an IPv6 port scanner?
An IPv6 port scanner is a specialized tool that examines network connectivity by probing ports on IPv6 addresses. It identifies which ports are open, closed, or filtered and detects the services running on those ports. This is essential for security auditing, network troubleshooting, and ensuring your IPv6 infrastructure is properly configured.
Is PortScan6 really free?
Yes, PortScan6 is completely free and open source. There are no paid tiers, premium features, or subscription fees. All functionality is available to all users at no cost. We believe in providing powerful security tools that everyone can use, regardless of budget.
Is PortScan6 safe to use on production networks?
Yes, PortScan6 is designed with production environments in mind. Our scanning engine uses non-intrusive techniques and carefully manages network load to avoid disrupting services. You can control scan intensity from lightweight to comprehensive, and even schedule scans during off-peak hours. However, we always recommend notifying your security team before running extensive scans.
How accurate are the scan results?
PortScan6 achieves high accuracy through our multi-verification scanning methodology. We use several different techniques to confirm port states and service detection, significantly reducing false positives and negatives. Our scanner also adapts to network conditions in real-time to maintain accuracy even on high-latency or unstable connections.
Can I scan multiple IPv6 addresses simultaneously?
Absolutely! PortScan6 supports batch scanning through several methods: manually entering multiple addresses, uploading CSV files containing IP lists, or specifying subnet ranges using CIDR notation. Our intelligent load balancing ensures efficient scanning of multiple targets without overwhelming your network or the target systems.
What operating systems does PortScan6 support?
PortScan6 is available for Windows, macOS, Linux, iOS, and Android. We develop native applications for each platform to ensure optimal performance and a consistent user experience across devices. Additionally, we offer a web-based version that works in any modern browser, allowing you to run scans without installing software.
