Advanced network scanner for detecting duplicate IP addresses using ARP scanning, OS fingerprinting, and hostname resolution.
IP address conflicts occur when two or more devices on the same network attempt to use the same IP address. This leads to connectivity issues, network instability, and downtime. The IP Conflict Detection Tool scans your network using ARP requests, identifies duplicate IPs, and provides detailed information about each device – including MAC address, operating system, and hostname.
This tool is designed for network administrators, IT professionals, and power users who need to quickly identify and resolve IP conflicts across large networks.

What is an IP conflict? An IP conflict occurs when two or more devices on the same network are assigned the same IP address, causing connectivity issues and network instability.
How does this tool detect IP conflicts? The tool sends ARP requests to all IPs in the network range. If multiple devices respond to the same IP, a conflict is detected.
Do I need administrator privileges? Yes. ARP scanning requires root or administrator privileges to access network interfaces.
Does this work on Windows? Yes. Windows 10/11 with WSL (Windows Subsystem for Linux) is supported. The tool also works natively on Linux.
Is this tool safe to use? Yes. The tool only sends ARP requests and does not modify any network settings. It is read-only and safe for network diagnostics.
What if my antivirus flags the tool? ARP scanners are sometimes flagged as false positives. Temporarily disable real-time protection or add an exception for the tool directory.
Can I use this on a Wi-Fi network? Yes, but client isolation must be disabled on the Wi-Fi network for ARP scanning to work properly.
