Device two: A printer with the IP address 192.168.1.200.Device one: Your PC with the IP address 192.168.1.100.Say you have three devices on an IPv4 LAN with a /24 (255.255.255.0) subnet: To help get an idea of what can go wrong when IP conflicts occur, let’s start with a simple example. Generally speaking, when multiple devices on the same Layer 2 network respond to the same IP, connectivity to those devices becomes unpredictable. Exactly what will happen when an IP address conflict occurs depends on the specific devices in place and your network configuration.

What is an IP address conflict?Īn IP address conflict is a common network issue that occurs when two or more devices on the same network have the same IP.
