About:
arp-sk is a command-line utility designed for generating and injecting custom ARP packets into a network. It allows network administrators and security professionals to test network hardware and software under various ARP conditions. The tool provides fine-grained control over ARP packet fields for specialized network testing scenarios.

Key Features:

Custom ARP packet construction and injection
Command-line interface for automation and scripting
Control over source/destination MAC and IP addresses
Support for various ARP operation codes

Use Cases:

Testing ARP cache poisoning vulnerabilities in network devices
Generating ARP traffic for network performance benchmarking
Verifying ARP table behavior under stress conditions
Educational purposes for learning Layer 2 networking protocols

Alternatives:

scapy – Python-based packet manipulation library with broader protocol support but requires Python runtime
arping – Standard tool for ARP pinging and duplicate address detection, focused on discovery rather than traffic generation
hping3 – Versatile TCP/IP packet assembler and analyzer with ARP capabilities among many other protocols
