Something called the ARP (Address Resolution Protocol) translates an IP address into a MAC address. It is hardwired or hard-coded onto your computer’s network interface card (NIC) and is unique to it. Where IP addresses are associated with TCP/IP (networking software), MAC addresses are linked to the hardware of network adapters.Ī MAC address is given to a network adapter when it is manufactured.
And if you are connected using Wi-Fi device you also have the Wi-Fi device.Įvery NIC has a hardware address that’s known as a MAC, for Media Access Control. If you are connected to the network (both for local or internet) using cable you certainly have a device called NIC (Network Interface Card).
