What is the use of IP address and MAC address?
The IP address is used to transport data from one network to another network using the TCP/IP protocol. The MAC address is used to deliver the data to the right device on a network.
Why do computers have both an IP and a MAC address?
So again, IP Addresses are logical and routeable addresses. And that’s why computers have both MAC Addresses and IP Addresses. MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.
What is the difference between the MAC address and IP address which layer of the OSI model does each operate at?
Implementation Layer: The IP address or logical addressing is implemented in the Network layer of the OSI or TCP/IP model. On the other hand, the MAC address or physical addressing is implemented in the Data-Link layer of the OSI or TCP/IP reference model.
What is MAC address used for?
A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
Can two devices have same MAC address?
If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. Duplicate MAC Addresses separated by one or more routers is not a problem since the two devices won’t see each other and will use the router to communicate.
Can you be tracked by your MAC address?
There isn’t a way to find a stolen computer from the MAC address or to find the identity behind one of these addresses. Much like IP addresses, MAC addresses are assigned to network devices and are easy to determine with tools like Command Prompt.
How do I locate a MAC address?
