Python's built-in ipaddress module handles subnets, host iteration, overlap detection, and subnetting for network engineers — no pip install required.
What is Linux Swap? Think of your computer's memory (RAM) as your physical desk. When you're actively working on projects (running applications), you keep the documents on your desk for…
A complete, device-agnostic walkthrough for building a road-warrior OpenVPN server on an OPNsense firewall (running on a Zimaboard), then connecting iPhone, Android, MacBook, Windows, and Linux clients to your home network.
Day 7 closes Week 1 of the Python for Network Engineers series. Read and write files cleanly with `with`, catch only the exceptions you mean, and use the standard logging module so your scripts leave a real paper trail.
Day 6 of the Python for Network Engineers series. Define functions, use *args/**kwargs the way Netmiko expects, write your first reusable module, and learn the __name__ == '__main__' guard.
Day 5 of the Python for Network Engineers series. if/elif/else, for, while, break, continue, plus enumerate/zip/range — wired against a real device inventory.
Day 4 of the Python for Network Engineers series. The four built-in containers — list, tuple, dict, set — and which one to reach for when modeling devices, inventories, VLAN lists, and config drift.
Day 3 of the Python for Network Engineers series. Indexing, slicing, split/strip/replace/join, and f-string formatting — the small set of built-in string operations that handles most CLI-output parsing.
Day 2 of the Python for Network Engineers series. Variables, types, indentation, the colon, truthiness, and the handful of syntactic rules that account for 90 percent of beginner mistakes.
Day 1 of a 21-post daily series. Why Python beats Bash and Tcl for network work, how to install it cleanly with a virtualenv, choose an editor, and pick a lab you can break.
