Command “arp -a” Displays the ARP (Address Resolution Protocol) table, showing IP addresses and corresponding MAC addresses of devices on the network.
- For Windows:
- Open Command Prompt as an administrator.
- Enter arp -a.
- For Mac:
- Open Terminal.
- Enter arp -a or arp -an.
- For Linux:
- Open Terminal.
- Enter arp -a or arp -n.
You will view a list of IP addresses and MAC addresses of connected devices on your screen.
Method 3: Check the Unknown Device Hostname Using its IP Address
The “ping -a <IP Address>” command provides the corresponding hostname using its IP address. you can identify the device by using its IP address and MAC address, the information can be obtained by pinging the device on your command prompt on your Windows Devices. This is done by following steps (For Windows): –
- Open Command Prompt/Terminal.
- Type “ping -a <IP Address>” and press Enter.
Check For All Connected Devices On Android and iPhone
Let’s understand how you can check for all connected devices on smartphones i.e. Android and iPhone using three different methods:
Method 1: Using Router’s Web Interface
- Connect to the router’s Wi-Fi.
- Follow the above steps specific to the router.
Method 2: Using Scanner Apps
- Install a network scanner app from the Play Store or Apple Store.
- Open the app and scan your local network.
- Identify connected devices and view their details.
Some commonly used tools are:Auvik, Intruder, SolarWinds, NetScan Tools Pro, and NMap.
