In this episode we talk about switching. We cover ARP, and some security options from a comment on Reddit. This will be an ongoing theme for at least a couple of episodes. We need to figure this out for our Raspberry Pi data center. There’s a lot to learn.

CORRECTIONS

The explanation of ARP is wrong. ARP will send a broadcast to all hosts. The host with the correct IP address will respond. We will cover this in the next episode.
