Ip Address Allocation Sequence; Dhcp Server Configuration Task List - HP 4800G Series Configuration Manual

DHCP requests is 1.1.1.130/25, the DHCP server will select IP addresses for clients from the 1.1.1.0/24
address pool.
Keep the IP addresses for dynamic allocation within the subnet where the interface of the DHCP server
or DHCP relay agent resides to avoid wrong IP address allocation.

IP Address Allocation Sequence

A DHCP server assigns an IP address to a client according to the following sequence:
1) The first assignable IP address found in the extended address pool referenced on the receiving
interface
2) The IP address manually bound to the client's MAC address or ID
3) The IP address that was ever assigned to the client
4) The IP address designated by the Option 50 field in a DHCP-DISCOVER message
5) The first assignable IP address found in a proper common address pool
6) The IP address that was a conflict or passed its lease duration
If no IP address is assignable, the server does not respond.
Option 50 is the requested IP address field in DHCP-DISCOVER messages. It is padded by the client to
specify the IP address that the client wants to obtain. The contents to be padded depend on the client.
