I hate to generalise, but most people are either really good with computers and networks (and able to describe them) or are completely shite. The majority of the comments here regarding the IP addresses lack an understanding of networks. First of all, there are numerous ways to expose an internal network to the Internet. There is the very common method of NATing, which basically means that Internal IP’s all have the same external address (the internal clients would have been given an IP from a DHCP server) but once they go past the firewall/router they have the same external IP. It’s obvious in this situation that this library DOES NOT USE NATing. It seems as if each computer is instead assigned a valid external IP address, very common for educational centres (because they get assigned large chunks of addresses for practically nothing)
