Got it.  renew is when it starts trying again.  rebind is when it
looks for a new server.  expire is when the actual lease expires.

So most likely this lease was last renewed at 20:44:34.

So my question now is: is there always a 2 hour wait between renew and
expire, or is the lease time just halfed?

Thanks,
Will

=>renew time does not match the dhcp-lease-time.
