What is the difference between a MAC address and an IP address?
A MAC (Media Access Control) address is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. MAC addresses are used to identify devices at the data link layer of the OSI model and are typically used for local area networking. On the other hand, an IP (Internet Protocol) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol to communicate.
While IP addresses can change over time, MAC addresses are generally fixed and unique to each device. This makes MAC addresses more reliable for identifying devices on a network. When checking who’s using your WiFi, it’s essential to note both the IP and MAC addresses of unfamiliar devices, as this information can be used to block the device from accessing your network in the future.

Enter the MAC address of the device you want to block, and set the access control to “Block” or “Deny.” Save your changes, and the device will no longer be able to access your network.
Alternatively, you can also block devices using your router’s firewall settings. Look for the “Firewall” section in your router’s web interface, and add a new rule to block traffic from the device’s IP address. Make sure to set the rule to block both incoming and outgoing traffic to prevent the device from accessing your network. Save your changes, and the device will be blocked from accessing your network.
Can I use WiFi analyzer apps to detect unknown devices on my network?
Yes, WiFi analyzer apps can be used to detect unknown devices on your network.
