I think it's more likely to mean that another host on the network is
using the address that DHCP assigned to the machine in question.
[dhclient tries to ping the address before starting to use it, and
will refuse to use it if a response comes back]  I tend to think that
such a problem will have to be solved by the service provider,
although some DHCP servers will give you a different address if you
provide a different client identifier.
