If you have ever seen the message “Windows has detected an address conflict IPYou may have wondered what that might mean. While the issues of conflict of IP they are not usually difficult to correct, they are often confusing, especially for those who are new to networking.
Let's see what an address conflict is IP, how it happens and the steps you need to take to correct this error when it occurs.
What is an address conflict? IP;
An address conflict IP (IP Conflict) occurs when two or more devices on the same network have the same address IP. To explain why this is a problem, we must take a step back and see what are IP addresses.
OR IP is essentially a unique number of the type xxx.xxx.xxx.xxx (IPv4), where each xxx group is a number from 0 to 255. Example something like 192.168.120.141. This form of one IP is version 4 and is intended for both internal IPs as well as for external ones. That is, for those that you use in your network but also for those that are used around the world.
Their number is limited from 0.0.0.0 to 255.255.255.255, ie a total of 4.294.967.296 possible unique addresses, a very small number for the development of the World Wide Web, and for this reason version 6 has been released. IPs have the format xxxx: xxxx: xxxx: xxxx: xxxx: xxxx.xxxx (IPv6) and each group receives both letters and numbers so their number can reach the number 3,403 × 1038 unique addresses.
As is a physical home address for receiving mail and (unfortunately) PPC bills, so are addresses IP act as a way to locate your computer on a network. Your router uses these addresses IP to direct network traffic to the correct devices.
But since two computers can not have the same address IP, how does the error occur?
How an address conflict occurs IP;
In most cases in modern networks, conflicts IP are rare. This is because of DHCP (Dynamic Host Configuration Protocol), a system used by routers to deliver addresses. IP.

With DHCP, when you connect a new device to your network, your router gives you an available address IP from the team IPs he has to choose. The device uses this IP for some time, until the need to use it ends and then if it is needed again it must get a new one. Unless your router is malfunctioning, two devices should never have the same address IP from this system.
Most commonly, conflict may arise IP when assigning static addresses IP on your network. Instead of automatically selecting a DHCP address, you can set up a network device to always use the same address IP that you specify for a specific device. This IP which is always fixed for a particular device is called “static address IP".
On the contrary the addresses IP which are not fixed and change each time depending on what numbers are available each time free to use, are called "dynamic addresses IP“. If you enter the same static address on two devices incorrectly, you will make a duplicate error IP.
Another conflict scenario IP This can happen if you have two DHCP servers on your network (something you should avoid). For example, you may have connected your own wireless router to your ISP router. If both devices try to act as routers, they may deliver dual addresses IP.
Finally, you can enter duplicates IP to the network when a machine returns to it after it is in standby mode. For example, say you leave your laptop idle for two weeks. During this period, the router may revoke the address IP of the laptop and assign it to another device, such as your phone.
When you turn on the laptop again, it may think it still owns this address IP, resulting in an address conflict IP. This can also happen if you put your computer on another network and you have set a static one IP which coincidentally uses the same group IP on your own.
How to resolve an address dispute IP
Like all network troubleshooting solutions, the first step you need to do is restart your troubleshooter and networking equipment.
If restarting all devices does not resolve the issue, then the problem is a little deeper. You will need to do the following test to see if your computer uses a static address IP.
If you are running Windows, open Settings and go to Network and Internet> Status. Click "Change adapter option" a little further down.
Then, in the window with your connections, double-click the network connection name.
On the resulting screen, click Properties.
Then double-click "Internet Protocol Version 4".
There you should see “Auto Address Performance selected IP”(Obtain an IP address automatically). If not, select it and press OK. Repeat these steps for Internet Protocol Version 6, and when done, see if the conflict is over.
Right-click the Start button and select "Command Prompt" or "Windows PowerShell". Type the following command and press Enter to leave the current address IP you have now:
ipconfig / release
Then use the following command to get a new address IP from the router:
ipconfig / renew
Check your router for conflicting devices
If the above steps do not fix the problem, you should then log in to your router's control panel and take a look at the connected devices. How you do this will depend on the model of your router, so we can not give exact instructions.
Usually in your router menu, you will find a list of connected devices under a section titled Connected Devices or My Network or something similar (Attached Devices, Connected Devices, DHCP Clients, My Network). Take a look at each device and watch out for dual addresses IP.
Update your router firmware
A faulty router can often cause conflicts IP and even without warning. If you still have address conflict errors IP even after performing the above troubleshooting, you will need to update your router firmware.
The exact steps for this also depend on the router you have. You will usually find a firmware update option when you log in to your router's control panel. This can be under an advanced menu or something like "Tools" etc.
While some routers allow you to update the firmware automatically through their menu, others require you to download a file from the manufacturer and upload it to your router. Check your router manufacturer's website for more help.
Now you know what an address conflict is IP, how two devices could get the same address IP and how to fix it. Most of the time, a collision will not occur in the average home network. And if it does, you can usually fix it with a few quick restarts.
