Here is how you can check it: On an unaffected host on the same network, open up a command prompt. On a Windows machine, type “arp -a [suspected duplicate IP]” and hit enter. On a Mac or Linux machine, type “arp [suspected duplicate IP]” and hit enter.

How do I troubleshoot a duplicate IP address?
Open Windows Explorer.
- Open Windows Explorer.
- Go to Network.
- Go to a Command Prompt and ping the host name of the device you are trying to identify the address of.
- You can repeat this process to the other devices until you find the IP Address that has been assigned to the printer.
Why does my network have 2 IP addresses?
It’s because your Ethernet (cable) network card and your WiFi network card is just that, two different network interfaces. That means that to function, each of them have to have an IP address, given by your router. It’s normal behaviour.
How do I fix IP addresses on my network?
Windows has detected an IP address conflict Quick Fixes
- Solution 1: Restart your router.
- Solution 2: Disable then re-enable your network adapter.
- Solution 3: Release and Renew Your IP Address.
- Solution 4: Remove Static IP.
- Method 1: Update your driver from Windows itself.
- Method 2: Update your drivers with a third-party app.
Can 2 devices have the same IP address?
An IP address conflict occurs when two or more devices on the same network are assigned the same IP address.Because of this setup, no two devices can have the same IP address on one network. If this happens, the network becomes confused by the duplicate IP addresses and can’t use them correctly.
Can router have multiple IP addresses?
Routers typically have multiple IP addresses. They have (at least) one IP for each LAN (well, at least if it’s an IP LAN) and usually one (sometimes more, but usually one) address attached to a “loopback interface” for management purposes.
How many IP addresses can a device have?
IP networks in your home network
As we mentioned earlier, each part of an IP address can have a value between 0-255. So the fourth part of the IP address permits for 256 different addresses (zero up to 255) that can be used for computers, IP phones, routers, laptops, printers and other devices.
How do I change duplicate IP address to preferred?
Type the command “ipconfig /all”.
Here’s how to set the duplicate IP as the preferred IP:
- Go to the regedit.exe:
- Locate this registry key:
- New, and click DWORD Value.
- Type ArpRetryCount.
- Right-click the ArpRetryCount registry entry and click Modify.
- Shut down the VM and start it again.
How can I get the same IP address?
As I understand it, two computers cannot have the same public (external) IP address unless they are connected via the same router. If they are connected via the same router, then they can have (share) the same public IP address yet have different private (local) IP addresses.
What is duplicate IP address?
NOTE: A Duplicate IP Address error message occurs when another device, such as a Laptop, Desktop, Cell Phone or Tablet has connected to the Network, and obtained the same IP Address from the DHCP Server that is in use by the Printer.
Do all devices on a network have the same IP?
No. Most personal computers are configured to ask the WiFi router to assign them an IP address upon joining the network (using DHCP). Most good routers will assign a unique IP address to each machine (particularly each network interface) a different IP address. Read more about DHCP to understand the process better.
Is IP address linked to WiFi or device?
IP addresses are permanently associated with the network, not the computer. When your computer connects to a network (e.g. via wifi), the network that you connect to assigns you an IP address for the duration of your connection.
What is second IP in router?
Using secondary IP addresses on the routers or access servers allows you to have two logical subnets using one physical subnet. Many older networks were built using Level 2 bridges. The judicious use of secondary addresses can aid in the transition to a subnetted, router-based network.
How do I get multiple IP addresses from ISP?
Go to WAN >> Internet Access, select “Static or Dynamic IP” or “PPPoE” for Access Mode, and click Details Page. Select “Specify an IP address” under IP Network Settings, and input one of the WAN IP Address, subnet mask and gateway IP address that your ISP has provided.
How do I connect two IP addresses to my router?
Connect the “LAN” port to the “network 1” network and give it a static IP address in the “network 1” subnet. Disable any DHCP server on the router. Connect the router’s “Internet” port to the “network 2” network and give it a static IP address in the “network 2” subnet.
How can I tell if two computers are on my network?
You need to know the subnet mask. The subnet mask tells you which bits of the address represent the subnet, and which bits represent the host within the subnet. If your subnet is a /24 (255.255. 255.0), then any address whose first three octets match would be in the same subnet.
What is the use of apipa?
APIPA stands for Automatic Private IP Addressing (APIPA). It is a feature or characteristic in operating systems (eg. Windows) which enables computers to self-configure an IP address and subnet mask automatically when their DHCP(Dynamic Host Configuration Protocol) server isn’t reachable.
How can another computer have the same IP address as mine?
This problem, though rare, can occur because of the following reasons:
- Two computers are assigned the same static IP addresses.
- One computer is assigned a static IP address that falls into the DHCP range for the local network and the same address is assigned to a computer by the DHCP server.
Why does IP address say duplicate?
Someone else probably has a lease on the preferred address. Duplicate is what it says when windows detects an IP address conflict (and then probably switches to another address).
How do I know if an IP address is already in use?
A reliable way to check that an IP address is not already in use is to logon to a machine that is in the same subnet as the Storwize® V7000 Unified system will use for management communications. Then ping the new IP addresses. For example, ping each of the IP addresses that you intend to use in the InitTool.exe.
Is everyone’s IP address different?
Whenever You are connected to the Internet always you have two ip addresses. your public ip and your private ip. Your IP address has to be unique for you to access Internet. For example, if you have multiple computers within your home you may want to use private IP addresses to address each computer within your home.
