In a MAC address, one hexadecimal digit resembles a group of four contiguous binary bits, called a nibble. MAC addresses are binary numbers which are represented in its hexadecimal equivalent. ![]() The scope of a MAC address is limited within a Local Area Network (LAN). MAC addresses are typically locally specific. ![]() MAC (Media Access Control) addresses are hard-coded into network adapter. MAC addresses are theoretically permanent numbers, which are burned into the network card.Įvery network adapter has a MAC (Media Access Control) address assigned to it when it is manufactured. The purpose of representing the binary address in hexadecimal format is to make it easier for humans to read and understand. followed by the decimal value.Media Access Control (MAC address or Layer 2 addresses or physical address or hardware address) addresses are 48 bit (six bytes) binary addresses represented in hexadecimals. It basically treats the string as a grouping of two-hex-digit sections, handling the front one (which may only be one character long if the string length is odd) then stripping that off and processing the rest of the string recursively.įor each section other than the first, it outputs the. Here's one way to do it as a general purpose solution, being able to handle any length hex string:
