Today we will learn about the are what is the arp in network and what is the work of it.
ARP (Address Resolution Protocol) is a network protocol used to find out the hardware (MAC) address of a device wants to communicate with some other device on a local network (For example on an ethernet network that requires physical addresses to be known before sending packets).
The sending device uses ARP to translate IP addresses to MAC addresses. The device sends an ARP request message containing the IP address of the receiving device. All devices on a local network segment see the message, but only the device that has that IP address responds with the ARP reply message containing its MAC address. The sending device now has enough information to send the packet to the receiving device.
ARP (Address Resolution protocol) request packets are sent to the broadcast addresses (FF:FF:FF:FF:FF for the Ethernet broadcasts and 255.255.255.255 for the IP broadcast). So this is all about the ARP.
