IP conflicts occur when two or more computers or devices (like a tablet) in the same network end up being assigned the same IP address. An IP (Internet Protocol) address is your computer’s unique identifier, comprised of a string of numbers, such as192.168.8.4. Without one, you can’t connect to the network. Usually a sort of warning or error message will pop up, alerting you of the problem. Sometimes these issues resolve themselves, but that’s not always the case.

 

Usually, IP address conflicts occur on a LAN (local area network), although they may also be seen between multiple devices connected to the Internet. Any device that has an IP address could potentially have a conflict with another device.

 

An IP address can be either static or dynamic. A static IP address never changes and is manually assigned. Dynamic IP addresses, on the other hand, are only temporary and a new one is assigned every time your computer or device connects to the Internet or your router.

 

Conflicts can happen with both static and dynamic IP addresses, although they are less likely to occur with static addresses today, because typically a DHCP (dynamic host configuration protocol) server, which is built into most routers, is used to manage and assign IP addresses. DHCP servers have a pool of IP addresses, called a scope, and from that pool addresses are assigned to devices in response to a system request for an IP address.

IP address conflict means same IP address is used by two or more device in same network. Using more than two DHCP server of same scope may lead to IP conflict. Other chance of occurung IP conflict is by manuallay configuring the IP address. The solution for IP conflict is simply change the IP address to new one
