Hands-on networking lab write-ups built around Containerlab, Cisco images and real configs, with measured results such as RAM use, packet captures and feature test outcomes. Readers get reproducible topologies, commands and honest limits on what each test showed.

Long-form technical write-ups on data center networking for AI infrastructure, including GPU serving fabrics, VXLAN EVPN migrations to Cisco NDFC, and AI-assisted network operations. Each post walks through real builds with configs, errors encountered and the design reasoning behind them.

A serialized technical build log following one engineer constructing an AI-driven, self-monitoring carrier network lab using Containerlab, Prometheus, BGP and Python. Each installment documents a phase of the build with real commands, code changes and candid notes about what worked and what was only a stub.

Packet Coders publishes practical network automation content, including walkthroughs of its Netpicker compliance platform and AI assistant, Python code tips for LLM cost tracking, and NetBox plugin release notes. Readers get hands-on, code-level guidance for engineers learning to automate network operations.
