On a laptop with multiple network interfaces, such as an Ethernet card (RJ45 connector) and a WiFi card (WiFi antenna), each interface has its own unique network address.
These addresses allow the computer to connect to different networks or to the same network through different means, each with its own access path.
For WIFI antenna, the network address that is assigned is generally a dynamic IP address given by the DHCP server of the network to which the computer connects. This IP address may vary from connection to connection, depending on the configuration of the DHCP server and the network you connect to.
In a home environment or small corporate network, this address will generally be in the same subnet range as the other devices on the same WiFi network.
Like the Ethernet interface, the WiFi card also has a unique MAC address, which is a hardware identifier assigned by the manufacturer, and this MAC address is constant, unlike the IP address which can change depending on the network you connect to. connect.
In short, the address of the WiFi antenna on a laptop is an IP address provided by the DHCP server of the WiFi network to which it connects, and this address can change each time the laptop connects to a different network or even to the same network at different times.
