step #3 can be done either by the client or by the DHCP server.
(well, some DHCP servers can do it.  probably not all.)

in any case, the busybox DHCP client can't currently do this.

(i've never studied or used the busybox DHCP server, but i
suspect it can't do any of it either.  but you were probably
asking about the client.)
