arping

In the realm of network troubleshooting and security monitoring, a variety of tools are necessary to diagnose connectivity issues, track network performance, and ensure security protocols are enforced. Most are familiar with the traditional ping command, which tests connectivity between two hosts on an IP network. However, there's a less commonly used yet equally critical tool for network administrators: arping. arping is a computer software tool that performs a similar function to ping but operates at the network layer using ARP (Address Resolution Protocol) rather than ICMP (Internet Control Message Protocol).
