8 If the final offer is not rejected, the IP acquisition sequence is

complete.

--End--

Case 2

The IP acquisition is unsuccessful if either the server or the client decides

not to participate, as follows:

• If the DHCP server cannot supply the requested information, it sends a

DHCPNAK message and no IP address is assigned to the client. This

can happen if the requested IP address has already been assigned

to a different client. See Figure 78 "IP acquisition sequence: Case 2"

(page 440).

•

If the client decides to reject the final offer (after the server sends a

DHCPACK message), the client sends a DHCPDECLINE message

to the server, telling the server the offer is rejected. The client must

restart the IP acquisition by sending another DHCPDISCOVER

message in search of another offer.
