Why do we need MAC address when IP address is there?

Why does Arp need MAC address?

Address Resolution Protocol is one of the most important protocols of the network layer in the OSI model which helps in finding the MAC(Media Access Control) address given the IP address of the system i.e. the main duty of the ARP is to convert the 32-bit IP address(for IPv4) to 48-bit address i.e. the MAC address.

WhAT can IP reveal?

IP addresses do reveal your geolocation, but not your precise location like a home address and never your name, phone number, or other precise personal information.

Why do we need MAC address when we have an IP address?

MAC addresses are used to send Ethernet frames between two stations in the same local area network. Each station has a unique MAC address that is used to identify who is the sender (source address) and who is the receiver (destination address). But Ethernet frames can’t travel between networks.

Is there routing based on a MAC address?

I almost forgot to mention: there is no routing based on MAC addresses. Low level ethernet and MAC addresses can only reach every device on the same network (cabled or wireless). If you have two networks with a router in between you cannot have a device in network A send a packet to the MAC address of a device in network B.

Can a device in network B have a MAC address?

If you have two networks with a router in between you cannot have a device in network A send a packet to the MAC address of a device in network B. No device in network A has the MAC address of the device in network B, so a packet to this MAC address will be discarded by all devices in the network A (also by the router).
