IP addresses are assigned as part of connecting to a network, and MAC addresses are assigned at the time hardware is manufactured.Īll devices on the same network have unique MAC addresses. IP Addressīoth MAC addresses and IP addresses are used by a TCP/IP networks for different purposes. The MAC address of your router’s internet connection will show up in packets sent further upstream, until that too is replaced by the MAC address of the next device - likely either your modem or your ISP’s router.Įven if someone knows your device MAC address, that knowledge certainly doesn’t help them do anything either good or bad. If you have a router, then your machine’s MAC address will go no further than that. That means that your computer’s network adapter’s MAC address travels the network only until the next device along the way. Typically MAC addresses are used only to transmit packets from one device to the next as data travels on a network. MAC Address is word wide unique, since millions of network devices exists and we need to uniquely identify each.
For communications within a network segment, it is used as a network address for most IEEE 802 network technologies, including Ethernet, Wi-Fi, and Bluetooth. MAC Address is also known as Physical Address of a network device. This is embedded into every network card (known as Network Interface Card) during the time of manufacturing, such as an Ethernet card or Wi-Fi card, and therefore cannot be changed. Media Access Control (MAC) AddressĪ MAC address is a 48-bits hardware identification number that uniquely identifies each device on a network. Now let’s see further information on MAC address. Both IP addresses and MAC addresses are unique identifiers, and together they make data transmission successful. Media Access Control Address (MAC) is a physical address which works at Data Link Layer.
In Computer Network various types of address are introduced each works at different layer.
All the data comes down to the network addresses, more commonly known as a Media Access Control (MAC) address. Whether you use wireless or wired network at your home or office you are not only need the network software but also the hardware ( such as routers, cables etc) transmit data from your device or computer to your ISP and vice versa from thousands of miles away from you.Īnd when transmitting data have to ensure the data reaches only you without being altered or overheard. You have definitely heard about the MAC address and you must know what is it?.
