![]() ![]() If the address of MAC for the destination is not available in the ARP table or cache, then the source will generate a request message of an ARP. If this destination address is available within the ARP table or ARP cache, then the source utilizes the address of MAC for communication. For this, the source will verify the ARP table or ARP cache with the destination of the MAC address. When the source at the network layer wants to converse with the destination, first the source requires discovering the Physical Address or MAC address of the destination. The example of address resolution protocol is discussed below. How does Address Resolution Protocol Work? ![]() Here, address resolution protocol works in between layers like IP & MAC ![]() The internet protocol address can be defined as the network layer which is accountable for forwarding data packets using different routers. This layer setups & finishes a connection in between two physically coupled devices so that transfer of data can occur. The MAC address or media access control address is also called the data link layer. So that the IT engineer is responsible for handling the specific layer. So that they can determine which network layer is affecting the device, application, or the installed software on the network. In the OSI networking model, there are different layers that provide an idea of what is going on with a specific networking system to IT teams. The address resolution protocol diagram is shown below. ![]() Address resolution protocol changes the 32 address bit into 48 address bit. An IP address is 32-bits long whereas a MAC address is 48-bits long. At present, the most frequently used IP is IPv4 (IP version 4). This mapping process is significant because the IP & MAC addresses the change & conversion of the length so that the systems can identify one another. ![]()
