Official announcements

I posted the slides from last week's recitation. I also posted the slides we didn't have the time to go through (in the form of a video, to capture the animations) under the title "Life-of-a-packet example." These latter slides show what happens (what packets are exchanged) when you do a DNS lookup from your computer. Please make sure they make sense and poll me if not (Discord is the best place to discuss/clarify outside class).
