Smartphones have unique MAC addresses for Wi-Fi and Bluetooth as in this iPhone example. Like Ethernet, Wi-Fi also requires an IP address, which can be viewed in Settings.

A mac address which is called as media access control address is a unique 48bit hardware address that is assigned to devices such as laptops, desktops, mobiles etc. 1 As per networking mac address works at the layer 2(data link layer) of the osi m Jul 10, 2017 · How MAC Address Filtering Works. RELATED: Don't Have a False Sense of Security: 5 Insecure Ways to Secure Your Wi-Fi. Each device you own comes with a unique media access control address (MAC address) that identifies it on a network. Normally, a router allows any device to connect — as long as it knows the appropriate passphrase. A dynamic MAC address is one that has been learned via an arp request. For example if a switch learns the MAC address from another device then it has dynamically sourced the MAC address. Say Computer A is connected to Switch-1, Switch-1 is connected to Switch-2 Now you issued command "#sh mac-address-table" in Switch-2 it will learn the The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing. The process of masking a MAC address is known as MAC spoofing. In fact, you can actually track people with this method if you really wanted to. For example, if I know the MAC address of my neighbors phone (which I could easily figure out) I could actually set up a computer that would watch for his MAC address and actually log when he leaves home (goes out of range) and when he gets home (back in range).

MAC-IP binding allows us to reserve static IP assignment for a client. The maximum supported entries are 32 and this feature is applicable for Local DHCP Scope only. Helps reserve IP address for specific client. Reserving an IP address allows us to create policies in the firewall configuration,

MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. MAC Address usually consists of six groups of two hexadecimal digits. switchport port-security mac-address mac-address. and. switchport port-security mac-address sticky . The 2nd command is used for dynamically assign the MAC Address to switchport when the device is connected to this port and when MAC is assigned to the switchport, it's permanently assigned to that port.

A MAC address is assigned by manufacturers and embedded into the device's network interface card -- it's permanently tied to the device, which means that a MAC address cannot be changed.
