If you are playing nicely, then you sent a DHCPRELEASE message to
the server (see RFC2131) before you logged off, and thus
relinquished your IP address for use by others.  Otherwise, you
are still using your IP address; RFC2131 makes no provision for
discovering that clients are not actually using assigned IP
addresses.
