IP Conflicts (And How to Avoid Them)

IP Conflicts (And How to Avoid Them)

An IP conflict happens when two devices try to use the same IP address on the same network.

Symptoms

• Device randomly loses internet
• Unreliable connectivity
• Router logs showing “duplicate IP”

Common causes

• Static IP set inside a DHCP range
• Two devices manually configured with the same IP
• Old DHCP reservations overlapping new static IPs

How to prevent conflicts

• Keep a documented IP plan
• Reserve a dedicated static range (e.g. .2–.50)
• Use DHCP reservations instead of manual static IPs
