How to See All IP Addresses on Your Network in Windows 10

To see the IP addresses on your network in Windows 10, open Command Prompt, type arp -a, and press Enter. It lists the IP address and physical (MAC) address of each device your PC has talked to recently. For a list with device names, open your router’s settings page.

Use the arp command

1. Open Command Prompt. See how to open Command Prompt in Windows 10.
2. Type arp -a and press Enter.
3. Look under your network’s Interface line. Each dynamic entry is a device on your network.

Entries ending in .255, or starting with 224 or 239, aren’t devices. They’re addresses Windows uses to reach many devices at once.

The list only shows devices your PC has contacted recently, so it may miss some. For a full list, use your router (below).

See the list in your router

Your router keeps the most complete list, often with device names.

1. Find your router’s address. It’s the Default Gateway when you run ipconfig in Command Prompt, often 192.168.1.1 or 192.168.0.1.
2. Type that address into a web browser. The router’s admin details are often on a sticker on the router.
3. Look for a page called Connected devices, Attached devices, Device list or DHCP clients.

Each router looks different. Check your router’s manual if you can’t find the page.

Use PowerShell

Open PowerShell and run:

Get-NetNeighbor -AddressFamily IPv4 -State Reachable,Stale

It shows the same kind of list as arp -a.

See devices in File Explorer

Open File Explorer and select Network on the left. It shows other PCs, printers and media devices that share themselves on the network. It doesn’t show IP addresses, and it only works when Network discovery is on.

Fill in the list by pinging every address

Because arp -a only lists devices your PC has talked to recently, you can make it more complete by pinging every address on your network first. In Command Prompt, run this, changing 192.168.1 to match the first three numbers of your own IP address:

for /L %i in (1,1,254) do @ping -n 1 -w 100 192.168.1.%i > nul

It takes a minute or two. When it finishes, run arp -a again and you’ll see more entries.

Find out which device an IP address belongs to

Run ping -a 192.168.1.23 with the address you’re curious about. If the device shares its name, it appears on the first line, such as Pinging LIVINGROOM-TV. If no name shows, match the MAC address from arp -a against the device list in your router, or look up the first six characters of the MAC address online to see the manufacturer.

If devices are missing

• The device is asleep or off. Phones and smart plugs often drop off the network to save power. Wake them and try again.
• It’s on a guest network. Guest Wi-Fi is usually kept separate, so those devices only show in the router.
• Ping is blocked. Windows PCs block ping by default on public networks, so they may not reply even when they’re online. The router list still shows them.
• You can’t open the router page. Make sure you typed the Default Gateway address exactly, with no www, and try a different browser.

Frequently asked questions

How do I find my own PC’s IP address?

See how to find your IP address in Windows 10.

I see a device I don’t recognize. What should I do?

Check the name and MAC address in your router. If it isn’t yours, block it or update your Wi-Fi security in the router’s settings.

Can I give a device a fixed IP address?

Yes. See how to change your IP address in Windows 10 for a PC. For other devices, most routers can reserve an address.

How do I open a shared folder on another PC?

See how to map a network drive in Windows 10.

Is there an app that does this for me?

Yes. Free network scanners such as Advanced IP Scanner list every device with its name and manufacturer in one click. Many routers also have a phone app that shows connected devices. The built-in methods above work without installing anything.
