![]() Well, finding an IP address from a MAC address is the topic we will be looking at in this article. Let’s delve right in, have a look at these two terms, and discuss what they are and why we need them at all. Define IP addressĪn Internet Protocol or IP address is a numerical label or address assigned to each device that is connected to a computer network that uses IP (Internet Protocol) for communication.Īn IP address serves two primary purposes: for host or network interface identification and location addressing of a connected device. This address can be assigned manually by configuring a device to save a Static IP Address, or automatically by a DHCP server (Dynamic Host Configuration Protocol server) which assigns a Dynamic IP Address.Īn IP address can be in the format of (IP V4) or abcd:efgh:ijkl:mnop:qrst:uvwx:yzab:cdef (IP V6). It is also always unique – no two devices on the same subnet can have the same IP address. If they do, it will cause an IP address conflict.Ī Media Access Control or MAC address is also a uniquely assigned address. ![]() Like an IP address, a MAC address also serves as an identifier for each device. But, in this case, the address is assigned to the hardware that is used to make the connection possible. In the case of a desktop or laptop computer, this hardware is the Network Interface Card ( NIC). MAC addresses are written in the “ AA:BB:CC:DD:DD:FF” format. The OUI is followed by a unique identifier since here too there can be no two devices with the same MAC address.įrom the image above, we can see that a MAC address is a hexadecimal number.ĪA:BB:CC) are used to identify a NIC’s manufacturer and are known as an Organizational Unique Identifier ( OUI).
