DHCP Client on the BIG-IP system sends host-name 'localhost' in DISCOVER packet after first boot. Note: The problem goes away after the first boot.
This can affect the lease given out by the DHCP server in the given network if the DHCP server is configured in such a way as to dynamically update the DNS based on the host-name option in the lease.
-- DHCP is enabled (this is the default on BIG-IP systems). -- Initial startup.
-- Empty the /var/lib/dhclient/dhclient.leases file. -- Run the following command: bigstart restart dhclient
