No, I'm sure I don't.
I should have said that the only reason this slightly annoys me
is that these warnings come up several times a day
in the logwatch on the server.

I guess the simplest solution would be to give a fixed address 
on my LAN to this blackberry, in /etc/dhcpd.conf on the dhcp server?
