IP Address Conflict In Microsoft® Windows® Network
Reasons for IP address conflict
An IP address conflict occurs when two systems on a local area network or the Internet have been assigned the same IP address. The IP conflicts between two computers normally render either one or both of them unfeasible for network operations. Several reasons for conflicting of IP addresses are such as when the system administrator assigns two computers on the LAN the same static IP address or if the system administrator assigns a computer a static IP address within the local network's DHCP range (dynamic IP range), and the same address is automatically assigned by the LAN DHCP server. It could be also possible if a malfunction in the network's DHCP server allows the same dynamic address to automatically be assigned to multiple computers or conflict might take place when an Internet Service Provider (ISP) accidentally assigns two customers the same IP address (either statically or dynamically).
Tips to fix IP address conflict are given below:
- Methods to fix Dynamic IP
- Technique to fix Static IP
- Tips to avoid IP address conflict
Methods to fix dynamic IP
Enter 'cmd' into the text box and click 'OK' after selecting 'Run' by clicking the Windows 'Start' button. This will open the Windows command prompt, then you have to enter "ipconfig /renew" in the space to refresh your dynamic IP address and hit 'Enter'. You may then open your network connection because the DHCP server manages IPs, it gives your PC an available IP address that is not already taken on the network. So, the next time you access network resources, you will no longer receive the IP conflict area.
Techniques to fix static IP
Initially, you should right click 'Network Neighborhood' on your desktop. But keep in mind that if it is a Windows Vista or Windows 7 operating system, the icon is labeled as network. Now you may select 'Properties' and right click your network card and select 'Properties'. For majority of the users, the network card is labeled 'Local area LAN Connection'. Subsequently, click 'TCP/IP' in the list of protocols and select the 'Properties' button underneath the list of protocols so as to enter a new IP address in the opened Window. Now you can click 'OK' to confirm your settings such that you can browse the network without the IP conflict error.
Some simple instructions to be remembered so as to avoid IP address conflict is to track what IP addresses have been assigned such that assigning the same address to two devices can be avoided. Also, notebooks that are taken off-site should not have assigned static IP addresses. Next step is to set the range for DHCP range outside of those that will be used for Static IP and also disable the sleep mode within the power settings to prevent the computer from going to sleep automatically. Users can rely on hibernate mode instead as this disconnects the computer from the network so that at once the computer is turned back on, it will obtain a new address through the DHCP.
