How to Find IP Address of Any Device On Your Network

The first step of troubleshooting any network problem is by pinging the IP address. Well, for that you need to know the IP address of the device or in cases IP address of all the devices in the network. There are several ways to do this and it entirely depends on the type of OS you are using. So, here are ways to find the IP Address of other devices in your network whether it is Windows, Android, iOS, Ubuntu and macOS.

Find IP Address of Other Devices on Your Network

In this article, we would be dealing with ways to find the private IP address of devices. Since the public IP address of all the devices within the same network remains the same i.e. the IP address of your router. In case, you are surprised by the word public and private IP address, it’s fairly simple. We have a detailed article on the difference between Public and Private IP and how to find the IP address of your own device.

1. How to Find IP Address in cmd For Network

The simplest way to do that in Windows is via the command line. To open the command prompt, type “cmd” on the Start menu. When you see the command prompt, right click on it and click on “Run as Administrator”.

CommandPrompt

In case you are using windows 10, you can directly run Command Prompt as an Administrator. Just right-click on the Start icon and click on Command Prompt(Admin).

Once you get the Command Prompt window, type the following command.

arp - a

This will display the entire list of ARP entries. In case you are wondering, ARP is a network utility which maintains a track of all private IP addresses in the network.

Find IP Address of all Devices on Network Using Windows App

Find IP addresses through the command line might be the simplest way but not the most intuitive one. If you are not good with command line then you should download this Nirsoft utility called Wireless Network Watcher. The app has a portable version as well as exe.

As soon as you open the app, it starts scanning your network. Give it some time and it will list up the active connections in your network. The app will display all computers, smartphones and smart homes devices that are currently connected to the network. Along with the Device Name and IP address, it also presents other relevant information like MAC Address, Device Information etc along with its IP Address.

2. Find all IP Address on the Network on Ubuntu

If you are working with Ubuntu or any Unix based OS then following are the ways. You can find the IP address using arp utility on the terminal. To open the terminal, right-click anywhere on the desktop and select “Open Terminal”.

Ubuntu_Open_Terminal

Alternatively, you can also click on the Activities button at the top-left corner. This will bring up a search bar. Type Terminal on it and click on the Terminal icon once it pops up.

SpotlightSearch_Ubuntu

Once the terminal window opens, type the following command.

arp -a

arp-a_Ubuntu

Another intuitive way to do this is through GUI. You have to install a tool called Angry IP Scanner. To install the Angry IP Scanner, you need to add an entry to the APT repository. APT (Advanced Packaging Tool) will then be able to fetch Angry IP Scanner from that particular location. To add the entry to the repository, type the following command

sudo add-apt-repository ppa:upubuntu-com/network

sudo-apt-getupdateRepository

In case you are facing any issues with IP Scan Installation, make sure you have disabled gpg signatures check. You can do that by using the following command.

sudo apt-get --allow-unauthenticated upgrade

Once the entry is successfully added, we need to update the apt-get repository. To do that, type the following command

sudo apt-get update

apt-get-update

Once the apt repository is updated successfully, we can install the Angry IP Scanner application. Type the following command to fetch and install the application

sudo apt install ipscan

IPScan_Install

Alternatively, if you have a browser you can also choose to install from the Angry IP Scanner website directly. Once you launch the app, it will the network you are connected to. Once, it is completed you can see the active connections in your network.

ipscan-ubuntu_minimised

It has advanced tools like opening an FTP, Telnet, SSH connection for any of the IP devices. One thing it lacks is the inability to show hostnames for the devices. Most of the devices come up as N/A in the hostname. This can, however, be found out by using the host command but that takes an extra step.

3. How to Find who is on my WiFi on macOS

On macOS, the steps are quite similar to that of Ubuntu. To find the IP Address of other devices in your network via the command line, we need to first open the terminal. To do that, hit Cmd + Space to trigger Spotlight Search. Type “Terminal” on the search bar. Click on the Terminal icon when the search results populate.

OpenTerminal_SpotlightSearch

Once the terminal window opens, type the following command.

arp -a

This will list down the IP’s in your local network with their MAC Addresses. IPs are listed in round brackets followed by the MAC Address.

Mac_Terminal_ARP_Results

You cannot see the hostname (name of the computer or smartphone) through the command line. For that, you will have to do a host search separately for each IP. For example, if I need to find the hostname of 192.168.1.105, then I have to execute the following command

host 192.168.1.105

host_name_mac_terminal

If the commands sound too much work, you can download a freeware from the Mac App Store called LAN scan. This app will list the IP addresses connected to the Local network along with other details like MAC addresses, Vendor etc. This app does not grab he Hostnames like Wireless Network Watcher. In order to get the hostnames of the devices, you need to get the premium variant. It can be purchased at a one-time fee of $7.

4. Android & iOS

On Android and iOS, there is no native way to check the IP Address of all the devices in the network. Hence, you will have to download a third-party app for this. Fing is a powerful network utility available for both Android and iOS which lets you scan your network. All you have to do is open the app and it will automatically start scanning all of the devices on your network. You’ll see all of their IP addresses, their names.

Unlike all the other apps we tested for Windows and Mac, Fing was the only that can figure out your connected devices brands and models. It can even fetch the device icon – wheater it’s an iPhone, MacBook, Router or Printer etc.

Apart from just scanning IPs, you can also ping them or see the open ports on the particular device.

5. Router

One of the most popular ways to check who is connected to your WiFi network is by using your router’s web interface.

In case you have access to the router web interface, you can simply log in to the web portal and check. The web portal address, username, and password are mostly printed behind the router. In case you don’t have physical access to the router, the web portal URL is mostly the PC’s gateway address. To find that, open command prompt and type the following command.

ipconfig | findstr "Default Gateway"

findGatewayCommand_CMD

The default username and password depends on the router’s manufacturer. Mostly, the username and password is “admin”. In case this doesn’t work for you, visit the official manufacturer site to get the default credentials.

Once you are logged in, look out for the Wireless or DHCP option. We need to navigate to the DHCP client’s list. On this page, you can see the entire list of devices connected to the network with their Client Name and MAC Address. You can also choose to block particular devices from this interface. To read more about it, check our article on how to block someone from your network.

Netgear_Router

The good thing about this approach is that you don’t have to install any software because you can access your router from any device. However, the only downside is that you need to know the router’s login credentials. If you are in a work environment then you might not have access to these details to log into the routers admin page. In that case, you will have to use the methods mentioned above.

Final Say

Once you have found the IP address of the devices in your network. You can start configuring your network accordingly. You can start assigning Static IP Addresses to your device, configuring SSH, access your computer remotely etc.
