For 64-bit MAC addresses, the IEEE developed the EUI-64 (extended unique identifier) standard. 64-Bit MAC AddressesĪs we have seen above, traditional MAC addresses are 48 bits in length. If you want to protect your network many routers use MAC addresses to restrict access to known devices. Let the MAC Address be 00:12:47:14:C8:29 The prefix (Manufacturer ID) is “00:12:47” which is ID for Samsung Electronics Co.,Ltd manufacturer.Įach device on a network has unique MAC address to be able to identify which device is which on the network. MAC addresses are 12-digit hexadecimal numbers ((0-9, plus A-F, capitalized) 48 bits in length, in order to make it easier to read most often it is written with a colon or hyphen separating every two digits, The ID number of the adapter manufacturer is present in the first 24 bits of a MAC address as assigned by the IEEE. The number given to the adapter by the manufacturer is defined by the second half (24 bits) of a MAC address. Media Access Control (MAC) address is also known as hardware address/ physical address which is is a unique value associated with a network adapter.
