MAC address (Media Access Control address) is a unique identifier assigned to network devices for communication on physical network segments. It is a 48-bit number typically represented in hexadecimal format, such as 00:11:22:33:44:55. Each device connected to a network has its own MAC address, allowing network switches and routers to identify and direct traffic accordingly. MAC addresses are essential for maintaining network security and ensuring proper communication between devices.
The importance of MAC addresses lies in their role in network management and security. They enable network administrators to monitor and control network access, detect unauthorized devices, and troubleshoot network issues. MAC filtering, a security measure, allows network administrators to restrict access to specific devices based on their MAC addresses, enhancing network security. Additionally, MAC addresses play a crucial role in network segmentation, dividing a network into smaller, more manageable segments to improve performance and security.
