This works. Yes, i think the schema really needs a update.

i have another question: when does the server free an ip-address? i tested a login with the same username within one minute and the server reserved two different ip-addresses. i thought, that the server will use the same ip-address for the second login, but the server doesn't.

Which behaviour is the right one?
