Address Resolution Protocol (ARP)ARP is primarily used to translate IP Addresses to Ethernet MAC Addresses.
ARP is a protocol that maps MAC addresses to IP addresses for packet delivery and for finding out which device in a LAN has a given IP address.

To view the ARP table, you can use the command arp -a in the command prompt on Windows or arp on Unix/Linux systems. This command displays the IP addresses and their corresponding MAC addresses that the device has recently communicated with. Additionally, on Linux, you can also use ip neigh to view the ARP table.
ARP, or Address Resolution Protocol, defined by RFC 826.

The primary purpose of the Address Resolution Protocol (ARP) is to map an IP address to a MAC address in a local network. This allows devices on a network to communicate with each other using their unique MAC addresses. ARP is crucial for proper functioning of Ethernet-based networks.

ARP is a Third layer or Network layer protocol. ARP is an address resolution protocol . The mechanism used by ARP to resolve IP address is look up table.
An empty ARP (Address Resolution Protocol) cache indicates that a device has not yet resolved any IP addresses to their corresponding MAC (Media Access Control) addresses. This situation typically arises when the device is newly connected to a network or has recently cleared its ARP cache. As a result, any communication attempts to other devices on the local network will require ARP requests to be sent out to obtain the necessary MAC addresses.
ARP buttons, or Address Resolution Protocol buttons, are typically found on network devices and are used to facilitate the process of mapping IP addresses to MAC addresses in a local area network. By pressing an ARP button, users can trigger the device to refresh its ARP cache, which can help resolve connectivity issues or ensure that the correct hardware addresses are used for communication. This function is particularly useful in networks where devices frequently change or where troubleshooting is needed.
The arp command line utility is used to view and manipulate the Address Resolution Protocol (ARP) cache, which maps IP addresses to MAC addresses on a local network. It allows users to display the current ARP entries, add or delete entries, and troubleshoot network connectivity issues. Typically, it can be run in various operating systems, including Windows, Linux, and macOS, with different options and syntax. For example, running arp -a displays the current ARP table on a system.
