The steps that occur as a DHCP client obtains IP address information from a DHCP server are:

HCPDISCOVER: When a DHCP client initially boots, it has no IP address, default gateway, or other such configuration information. Therefore, a DHCP client initially communicates by sending a broadcast message in an attempt to discover a DHCP server. DHCPOFFER: When a DHCP server receives a DHCPDISCOVER message, it can respond with a unicast DHCPOFFER message. DHCPREQUEST: The DHCP client communicates with the selected server by sending a unicast DHCPREQUEST message asking the DHCP server to provide IP configuration parameters. DHCPACK: The DHCP server responds to the client with a unicast DHCPACK message. This DHCPACK message contains a collection of IP configuration parameters
