â—† This command issues a BOOTP or DHCP client request for any IP interface that
has been set to BOOTP or DHCP mode through the ip address command.
◆ DHCP requires the server to reassign the client’s last address if available.
â—† If the BOOTP or DHCP server has been moved to a different domain, the
network portion of the address provided to the client will be based on this new
domain.
