Well, an IP address is the address of your device on a network that allows you to receive and transmit Internet traffic on your device. Every IP address, like cell phone numbers, must be unique to accurately identify each device connected to the network and transfer the desired information. For example, a router to which you are connected assigns an IP address to your computer. Often, two devices are assigned the same IP address in an unusual circumstance. As a result, you may receive a warning indicating an ‘IP Address conflict’ on your computer.
Fortunately, resolving the problem is relatively straightforward since it is not hardware-based and is generally very temporary. However, since this problem may occur for various reasons, you may need to attempt more than one of the solutions given in this guide. But before we go into how to fix the problem, let’s first look at how an IP address conflict occurs in the first place.
How Does The IP Address Conflict Happen?
An IP address may be assigned to a device in two ways. The first device is to use a router that employs the DHCP protocol and provides unique IP addresses to all devices connected to it. Another method is to set a static IP address to your device, which will stay the same anytime you attempt to connect to a network. The primary cause of IP address conflict is when a static IP address is issued to a device and subsequently connected to a DHCP-enabled network without first reserving that static address with your router. The router eventually allocates the address to another device, and the conflict arises. Another problem is when you accidentally provide the same static IP address to more than one device.
There is also the possibility that the router may fail and assign the same IP address to two or more devices. A conflict may also occur when a device becomes active after being in sleep mode for an extended time. Consider this: your computer has been dormant for many weeks. During this time, its IP address expired and was given to another device by the router. However, when the computer boots up, it still uses the same IP address, resulting in a conflict. However, the remedies provided in this guide will resolve these issues. Now that you’re familiar with the display of the problem let’s head on to resolving the problem on your computer.
Suppose you do not have any computers with static IP addresses and are still experiencing IP address conflict issues. In that case, it is recommended to restart the router first since a router malfunction is likely the main source of the problem. Restarting your router will immediately refresh the router system and renew leases on all of your devices by providing them with a new IP address. This should resolve your issue practically instantly. To manually restart the router, press the ‘Power off’ switch, which is normally located on the back of the router, to turn the power off. Then, after a few minutes, please turn on the router again to restart it. You may also use the web interface to restart the browser.
1 – Using your favorite browser, go to 192.168.0.1 or 192.168.1.1. Once the website has loaded, enter your router credentials (normally located at the bottom of the router) to access the system settings.
2 – On the next screen, locate the ‘System Tools/System’ option on the left sidebar and click it to expand the section.
3 – To continue, locate and click the ‘Reboot’ button in the enlarged section of the website.
4 – Next, read the information on the website and click the ‘Reboot’ option to restart your browser from the right section of the page.
The IP address conflict issue should be resolved after you restart your computer.
