I noticed in the video they talk about how IP addresses no longer go by country and region. I tried researching that a bit more myself. Is that because people can use a VPN to "hide" their location? That seemed a little odd to me, but it was the best my google searches could come up with.
I am having trouble understanding what it means that the addresses are hierarchical by "network", not region. What does a "network" look like? Is it connected to a specific router? Or, is it based on who your ISP is?
I know this goes beyond the scope of APCSP and I am not teaching this lesson until next week, but I thought I wold see if anyone had any suggestions out there.
Also, I found this online that I thought was helpful when thinking of additional examples of hierarchical addressing.
