Hi mkreder,
The place you’re referring to in the lecture was comparing multicast to unicast. I’ll take your suggestion under advisement for edits.

This bit of the class describes multicast incorrectly. The description is broadcast (everyone receives), but multicast is to specific IPs that nodes can subscribe to.
The metaphore (blue brothers) got me thinking about broadcast as well…
I always thought unicast was 1-1, multicast was 1-n and broadcast was everyone.
