Yes, thx. The pupils will be sitting at home and will dial up each other
to communicate their own ip number. But it would be nice if the started
the mastermind program and the program would say: "Hullo, your ip number
is ..., please communicate this to your mate." Of course they can use
ipconfig for finding out their data. But it would be more elegant if they
were told by their program.
