Hi and thanks a lot for your video lectures!

In the IPv6 cheat sheet it says

LINK LOCAL - Everything within the same collision domain that will not be routed (i.e. attached to the same switch).

I'm not sure "collision domain" is the right term, since when two or more hosts are connected to a switch via a Gigabit Ethernet cable each, they are not on the same collision domain, since their Ethernet frames can't collide, even when they send simultaneously.

Maybe "broadcast domain" is more suitable here.

Edit: Come to think of it, "broadcast domain" might not be a good fit either, since there are no broadcasts in IPv6. "Everything within the same subnet that will not be routed", is probably a safe way to put it.
