Does everyone in the same network have the same IP address?

Say if you're on a big network(at a school or something) and you have like 30 different computers with 30 different accounts, all using the same router/server. Will they all have the same IP address, and can a website tell if all 30 of them came from the same network(in other words, if you sign up for something on 30 different computers in the same network, is that the same thing as signing up for something 30 times on the same computer?Does everyone in the same network have the same IP address?
nope they all have different ones.Does everyone in the same network have the same IP address?
Everyone within the LAN has a unique LAN IP address, but it is the IP address either from the DHCP server, or if the TCP/IP settings is configured manually. But if all 30 computers exchange traffic to the WAN through only one line, then the outside world will only see one IP address coming from your LAN, which is the WAN IP address assigned by your ISP.

I have a LAN network created by me, on LAN(10 persons) we have different Ips but on the internet the IP is the same for all
