	As I recall, and I believe as is confirmed by a message from
	ISC which won't leap out of my mail archive just now, the
	difference is significant, and as follows.

	The first (with 'on') is a response to DHCPREQUEST;
	the second (with 'to'), to DHCPINFORM.

	As you probably know, REQUEST is used for address acquisition or
	renewal in order to establish or extend the client's connection
	to the network, while INFORM is used to request other (perhaps
	application-specific) configuration parameters.
