Situatie

Do you actually know everything connected to your home network?Between smartphones, laptops, televisions, cameras, printers, smart speakers and IoT devices, the answer is increasingly difficult to track.

Check Your Router

• The router is usually the best starting point.
• Open its administration interface and look for a section named something similar to:
• Connected Devices, Clients, Network Map or DHCP Clients.
• You will usually see IP addresses, MAC addresses and sometimes device names.

Check Your Computer’s ARP Table

On Windows, open Command Prompt and enter:

arp -a

The ARP cache shows IP-to-MAC mappings recently learned by your computer. However, this should not be interpreted as a guaranteed list of every device on the network.

Use PowerShell

Windows users can also inspect neighbors with:

Get-NetNeighbor

This provides information about devices discovered by the local networking stack.

Again, discovery depends on network topology and recent communication.

Use a Network Scanner

• Dedicated network-discovery applications can probe an IP range and identify active hosts.
• Network administrators often use tools such as Nmap for more advanced discovery.
• Only scan networks that you own or are authorized to administer.

What if you find an Unknown Device?

Don’t panic immediately.Device names can be misleading or completely absent.Compare the MAC address against your known devices and check the manufacturer information.Smart TVs, watches and IoT devices are frequently forgotten.

If a device genuinely appears unauthorized:

1. Change the Wi-Fi password.
2. Use WPA2 or preferably WPA3 where supported.
3. Disable obsolete security modes.
4. Review router administrator credentials.
5. Reconnect trusted devices.
