You are expected to comply and renew the lease; why not just do that?
What I (hesitantly) suggested is to change the network config to static,
not dynamic, at which point you'd have fixed (and stolen?) the IP you
were provided. I'm not familiar with a Debian LiveCD system (I have
used Knoppix and Ubuntu, both based on debian), so not sure of the details,
but presumably /etc/network/interfaces would exist in a RAM filesystem
and could be edited as needed. Alternatively, you could probably come up
with ifconfig commands to do this more directly.
