Build a Network Scanner with Python and Scapy

Imagine you’re sitting at your desk, wondering exactly which devices are lurking on your local network. Is that new smart TV actually connected? Did someone unauthorized join your Wi-Fi?

With Python and the powerful Scapy library, building a network scanner is not just possible; it’s surprisingly simple, and you can get it running today.
