PFQ School?!

Technically, yes, users from the same 'school IP' really refers to a group of different IP addresses... ish. Kind of. Say you have a router at home, and its IP address is, as an illustrative example that would never really happen, "0.0.0.1". Then every device on your home network - your phone, computer, smart TV etc - will tell servers to send their responses to 0.0.0.1. If several people are connected to your wifi, it will look like all of you are sending from the "same" IP... But also, and I'm omitting technical details because it gets confusing, your router essentially assigns an ID to your specific device, and it tells the server that ID so that the server, when it responds, can remind the router of which device is supposed to get the response. So the server would see something like, "Send this data to 0.0.0.1 and by the way remind me that it's for Device A." If your buddy logs on at the same time, the server gets a second request, "Send this other data to 0.0.0.1 and remind me that it's for Device B." So those could count as different "IPs," even though they're both going to 0.0.0.1, which is the same IP. IP addresses belonging to schools are going to work the same way, except that A) many universities have their own permanent IP addresses reserved for their router(s), and B) btw they, and anyone else, can use multiple routers. So a university could own a router whose address is 0.0.1.0 and another whose address is 0.0.1.1, and each router has different devices connected to it. That's technically two IP addresses, one for each router. But people will still refer to them as "the school IP address" because everyone knows they both belong to this particular university.

Plus if a K12 school had 100+ active PFQ users, that school would probably block the website from their own wifi lol. No fun allowed.
