[NTLUG:Discuss] dhcpcd guestion

[Fred James]

Sorry for the confusion - I don't care what the IP is, but I relocate my 
laptop twice a day (work/home) and therefore DHCP and routing 
information really does change twice a day.  If my machine thinks it 
still has the stuff it was using before the last shutdown then I can't 
get anywhere at all - therefore I must force for a new "lease" (is that 
the right term?).  I suppose some folks might have some other reason for 
wanting a new IP, but I don't know what it would be.
