PHP is a server-side web scripting language not designed for low-level network scanning or standalone automation scripts.

C# is a compiled, general-purpose application language that lacks the quick scripting workflow and native network security libraries suited for this task.

Python provides extensive networking libraries such as Scapy, python-nmap, and the built-in socket module that make network scanning and device discovery straightforward to implement. Its concise syntax and compatibility with scheduling tools like cron make it the standard choice for automating recurring security tasks such as daily unauthorized device detection.

ASP.NET is a web application framework, not a standalone scripting language, and is not appropriate for network-level scanning automation.
