Using netlab for Classroom Training with Sander Steffann

In March 2024, I received my first PR from an airplane: Sander Steffann was flying to South Africa to deliver an Ansible training and fixed a minor annoyance in the then-new multilab feature. Of course, I wanted to know more about his setup, but it took us over a year and a half till we managed to sit down (virtually) and chat about it, the state of IPv6, the impact of CG-NAT on fraud prevention, and why digital twins don’t make sense in large datacenter migrations.
