Windows Has Detected An IP Address Conflict
Windows Has Detected An IP Address Conflict This message appeared and you’re left with no clue which way to go. Could it be a virus? Are your computer or router inoperable? What do you do to resolve the IP account conflict? The first thing to remember is that it’s not a virus and you shouldn’t need to worry about your computer or router. An IP issue can be easily solved in a couple of easy steps. Check out this article to learn how.
What is the IP Address Assignment Process Work?
Each device that is connected to the network must be equipped with an IP address for communications purposes. It’s a unique identifier of the device. If it’s not there, that device won’t be able to communicate or even receive information. It’s not even able to connect to the internet.
The IP address could be either static or dynamic. Static is an address that is assigned to a device forever at the request of the end-user. Dynamic addresses are automatically assigned to the DHCP server. DHCP is the abbreviation in the form of Dynamic Host Configuration Protocol. It is the DHCP server is embedded in every router with wi-fi and is responsible for the assignment of an IP address automatically.
Apart from an IP address the DHCP server allocates a subnet mask default gateway, as well as a DNS server. Each device that is connected to your wireless network gets these identifiers through your router (from a DHCP server).
Every device that is connected to a network needs an IP address for communications reasons. That address is a unique identifier of the device. Without it, the device won’t be able to communicate or send information. It can’t even connect to the network.
The IP address could be dynamic or static. Static addresses are an address that is assigned to a device for life via the device’s user. A dynamic IP address will be automatically assigned to the DHCP server. DHCP stands for Dynamic Host Configuration Protocol. The DHCP server is embedded in each wi-fi router and is responsible for the assignment of IP addresses automatically. In addition to an IP address, a DHCP server also assigns a subnet mask default gateway and DNS server. Each device that connects to your wi-fi network is assigned these identifiers by your router (from a DHCP server).
The IP addresses in the pool by default are part of the same subnet that is it is the routing router’s IP default. For instance, the default IP of the gateway that is in the above example is 192.168.0.1, and all addresses in the DHCP pool come from the same subnet, namely 192.168.0.x (they all begin by 192.168.0).
The computer does not have an IP address that is dynamically assigned. The IP address is actually leased. It is possible to determine the length of the lease (Lease Time option in our example). The reason that addresses are being leased is to ensure we have enough addresses on our DHCP server that aren’t running in the absence of an address.
If your computer (or another device) attempts to connect to the wi-fi it will ask your router to provide the address and then your router (or more accurately, the DHCP server in your router) gives you the address that is the first to be available. If the lease period expires, the server determines whether the device is in use or not and renews the lease, if the device remains connected. If the device isn’t connected the address is redirected into the pool and made accessible again.
How Do You Assign a Static IP?
Certain devices, such as printers and network servers require a permanent IP address. They can’t be assigned an address that changes as their address needs to be fixed. The static IP addresses can be assigned to the user (manually) instead of automatically assigned by the DHCP server. It is possible to create a static IP address to any (or any) gadget connected to the wi-fi.
There are two options to assign an IP address with a static address for your gadget. It is possible to do this via your device’s settings for the network (your PC’s properties for TCP/IP) or create a DHCP reservation.
Method 1. Define an IP address that is static to your computer through your PC’s TCP/IPv4 setting.
To go to the TCP/IP settings, you’ll be required to launch your Network as well as Sharing Center Click on the Wi-Fi network you are connected to and go to Properties and scroll down until you see Internet Protocol Version 4 (TCP/IPv4) Double-click it.

In the settings for TCP/IPv4, you must select ‘ Use the following IP address and add all required details (the address you’d like to assign, the subnet mask, and standard gateway).
After that, click “Use the following DNS server addresses and then enter the preferred and alternate DNS server addresses.
Make sure to check the box “Validate settings after exit, and click on OK.

When you start your computer, it will receive a permanent IP address.
Method 2. Create a DHCP reservation
If you’re in a smaller network, where only a few users require static IPs the two methods of assigning static IPs are equally effective. However, if you are on an enormous network with a lot of devices that require static IP addresses, making the DHCP reservation for each device is the more efficient option. If you choose to make the DHCP reservation option, then you don’t need to alter TCP/IPv4 settings for each device. You can do all of the adjustments in one location.
To make a reservation you’ll need to open the control panel of your router (aka Configuration Manager (also known as GUI) and locate the DHCP settings (usually within the LAN settings). In the DHCP configurations, there must be a button that says make reservations’, ‘make a DHCP reservation or static lease’, or something similar to that.
If you want to create a static IP for your computer or printer or another device, you’ll need to enter the device’s MAC address along with an IP address you would like to use. In some instances, it is also necessary to enter the name of the device.
Based on the model of router depending on the model, you might need to enter all of the necessary details manually, or select the device from a dropdown list, and then type in the address you wish to use.
How to create a DHCP reservation (Ubee UVW3200)
Making a DHCP reservation is an efficient solution, particularly when multiple devices require static IP addresses. However, there are some disadvantages we’d like to point out. When connecting your gadget to a different network, it doesn’t have an IP address that is static (because the changes you’ve made only apply to the wi-fi network you’re connected to). Additionally, after you reset your router (we are talking about a hard or factory reset) all modifications you’ve made are deleted.
Note: When assigning a static IP through your PC’s TCP/IP settings, you should use an address outside the DHCP pool but from the same subnet as the default IP. In our case, that should be an address within the scope 192.168.0.2 -192.168.0.9. When assigning static IP through a DHCP reservation, you should use one of the addresses inside the DHCP pool. That is a generally accepted practice.
What Causes an IP Address Conflict?
A conflict in IP occurs when two devices are sharing an identical IP address. Two devices with identical IP numbers will become cut off from network communication and will not be able to connect with each other until you have resolved any IP conflict.
What causes the IP issue with an address? Could it be a problem with the router or human error? In reality, it’s a human error. IP conflict is not usually caused by a malfunctioning router. It’s far more often caused by the user’s/administrator’s mistake. This is, in most cases, closely linked to the setting of the static IP.
If, for example, give a static IP to your computer (whether through TCP/IP settings, or DHCP reservation) without checking to see if that address has already been being used by another device, you could create the IP to conflict. In addition, if you assign a static IP for your PC using TCP/IPv4 settings, and then assign the same address to a different device by using DHCP reservation you’ll cause the IP conflict.
In this instance, the streaming box on my network (my streaming box) already utilizes the address that I gave to my computer.
In both cases the two instances, the IP conflict was the result of my error. The reason for this was that I did not adhere to the good method I mentioned earlier. Therefore, again when you set an IP static through properties for TCP/IP, choose an address that is outside of the DHCP pool. When creating a static IP via DHCP reservation, choose an address within the DHCP pool (but make sure that the address isn’t currently being used).
How to Resolve an IP Address Conflict?
IP conflict can be a frustrating problem that is easily resolved. You can take a number of steps to solve an IP issue – reset your router, deactivate the network adapter, reverse the changes that you made in TCP/IPv4 configurations, or even use Command Prompt on your Windows PC.
Solution 1 – Reset your router
Resetting your router back to default settings can resolve the IP issue only when a fixed IP address has been created via the use of a DHCP reservation (on either of the devices or on both). If you made use of the settings on your device to assign an IP address that is static on both devices and your router was reset, it is not going to fix the issue. Therefore, if you set an IP static to your printer by using the printer’s settings, then afterward, you allocated the exact static IP for your computer or server with the properties of TCP/IP (not the DHCP reservation) Resetting your router won’t fix any IP-related issue.
Important: Resetting your router’s settings to factory defaults erases all modifications you’ve made to the router’s settings. If you have several devices connected to your network that use static IP addresses particularly when all addresses were created by DHCP reservations, then it’s wiser to check the router’s settings, locate those devices that have static IP addresses, then remove either or both of the devices that use the identical static IP. If you take off just one device and then reboot your router the IP address conflict will be resolved.
Solutions 2 – Edit the settings of your TCP/IPv4 (disable an IP static and then obtain an IP in a timely manner)
If you’ve configured a static IP on your computer You will need to return to the TCP/IPv4 settings (Network and Sharing Center ) > right-click the network > properties > TCP/IPv4).
To revert all previously modified settings, click the option to automatically Obtain IP Address and Find the DNS Server address automatically. Click on OK.
The simple change you make will solve the IP address conflict that you have If it isn’t working then consider the third option.
Solution 3 – Use Command Prompt
Solution 2 is typically utilized in conjunction in conjunction with Solution 3. After you have changed the TCP/IP properties back and defaults to the default setting, you can open the Command Prompt, and use the following commands:
Command 1. ipconfig/flushdns (Enter) -this command will restart the DNS server configuration.
Command 2 netsh Winsock reset (Enter) This command will reset the Winsock catalog. this command resets to the Winsock catalog and helps you recover your system from socket problems. It basically corrects any changes to the network configuration that are corrupted and resets all of the essential network settings back to their default values.
Optional: netsh int IP reset (Enter) This command resets the TCP/IP settings. Since you’ve already set the properties of TCP/IP to default settings You don’t need to do it.

Command 3 ipconfig/release (Enter) –this command lets you release the IP address that is currently assigned to your computer.
The command 4 is ipconfig”/renew” (Enter) – this command assigns an additional IP address to your computer via the DHCP pool.
After you have completed all of the above commands, quit the Command Prompt and then restart your computer. It is likely that this will fix the IP address conflict.
