Section: 4.1


Original Text
-------------
Normally, DHCP servers and BOOTP relay agents attempt to deliver
DHCPOFFER, DHCPACK and DHCPNAK messages directly to the client using
uicast delivery.


Corrected Text
--------------
Normally, DHCP servers and BOOTP relay agents attempt to deliver
DHCPOFFER, DHCPACK messages directly to the client using
uicast delivery.


Notes
-----
According to prior part description in section 4.1: "In all cases, when ’giaddr’ is zero, the server broadcasts any DHCPNAK messages to 0xffffffff.", the DHCP server should not send DHCPNAK in unicast to client unless 'giaddr' is not zero.
