E.g. if used from a script or another tool:

The original purpose of DHCPINFORM as specified by RFC2131 is when the
the client already assigned itself an IP address, typically with a
static configuration. So the script that configures the static address
can just call udhcpc once with the address that it configured.
As for the address of the DHCP server, most of the time it is the
default gateway, even through it is probably not a good idea to hardcode
that.
