Oct 13, 2017 · MAC addresses are not unique. There can be, and will be duplicates with MACs. There are several reasons for that, one being that they need not be (globally) unique. The MAC must be unique on the local network, so ARP/NDP can do its job, and the switch knows where to send incoming datagrams to.
Mar 18, 2024 · Until now, we know that MAC addresses identify a particular device in a network. So, we naturally can use MAC addresses to enable a device to communicate with other devices. It occurs indeed: the frame header carries a source and a destination MAC address.
Sep 14, 2024 · Learn what the MAC address is, how it is formed, and the types of MAC addresses (unicast, multicast, and broadcast). In network, an address provides a unique identity to an end device. Unless an end device has a unique address, it can’t communicate with other devices in the network.
Apr 7, 2018 · The hardware MAC address is unique to the network card, and can not be changed. However, you can in software easily change the MAC, but if the value is deleted it reverts back to the hardware MAC. 00:00:00:11:11:11. The first three represent the manufacturer that made the card.
1. Uniqueness: The most critical aspect of MAC addresses is their uniqueness. No two devices on a network should have the same MAC address. This ensures that data is sent to the correct device, preventing confusion and ensuring the integrity of network communication. 2. Device Identification: MAC addresses play a crucial role in identifying and ...
