How does a DHCP client get an IP address?
Figure 1: DHCP Request for an IP Address from a DHCP Server The client returns a formal request for the offered IP address to the DHCP server in a DHCPREQUEST broadcast message. The DHCP server confirms that the IP address has been allocated to the client by returning a DHCPACK unicast message to the client.

DHCP Configurations Received Are Invalid Configurations can be invalid for two reasons: The client determines by ARP that the IP address offered to it is in use elsewhere.

Why is Ubuntu DHCP not assigning IP address?
It is because in UBUNTU 15.10 (can’t speak about other version) during boot UBUNTU waits for all the auto interface to be UP. Owing to it UBUNTU waits for 2 mins 3 sec (in my case) and then completes the boot process. So in order to reduce the boot time and to not encounter this issue I am using allow-hotplug.
What happens if the DHCP address is not on the same subnet?
If it originated from the local segment, the DHCP server compares the requested address to the IP address and subnet mask belonging to the local interface that received the request. If the address appears to be on the same subnet, the DHCP server will remain silent even if the address isn’t in the range of its pool of addresses.
