However, there are other methods you can use. Using your router’s web interface is the ideal way of checking who’s connected to your WiFi.

Use a Network Scanner To See Who’s Using Your WiFi A good way to do this is to compare the device’s MAC address from the list to the MAC addresses of the devices you own that could be connected to your wireless network. However, before you do that, make sure to check whether it’s actually a stranger feeding off your WiFi, or one of your devices that you simply didn’t recognize. When you see a device you don’t recognise, your first intention will probably be to boot it off your network. You’ll see some sort of table that includes the hostname and MAC address for every device on the list. No matter what router you’re using, the list of connected devices normally offer the same information. While on Netgear, you need to look for Attached Devices. This means that 2 24 (= 16.777.216) unique OUAs can be assigned per OUI.On Verizon routers the section you need is called My Network.

Bit 25-48 (network adapter identifier): Bits 25 to 48 provide device manufacturers with 24 bits for assigning a unique hardware identifier (organizationally unique address, OUA).

A corresponding service is available, for example, on. The assignment of OUIs is usually public and can be determined via databases.

Bit 3–24 (manufacturer identification): Bits 3 to 24 encode an identifier (organizationally unique identifier, OUI), which is assigned exclusively to hardware manufacturers by IEEE.

Addresses that are only locally unique are called locally administered address (LAA) and are marked with U/L = 1. If U/L = 0, the address is valid worldwide as a universally administered address (UAA).

Bit 2 (registry): The second bit of the MAC address indicates whether it is an address with global validity (universal) or whether the address has been assigned locally (local).

Multicast addresses are identified by I/G = 1 and are addressed to several receivers. If I/G = 0, it is a unicast address for a single network adapter.

This bit is called I/G (short for individual/group). Bit 1 (receiver): The first bit of the MAC address specifies whether it is an individual or group address.The bit sequence of each MAC address is divided into 4 areas, each of which encodes different information.
