Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.

  1. Step 1: When the client computer (or device) boots up or is connected to a network, a DHCPDISCOVER message is sent from the client to the server.
  2. Step 2: When the DHCP server receives the DHCPDISCOVER request message then it replies with a DHCPOFFER message.

Can end users use dynamically assigned IP addresses?

End-user devices such as PCs typically have dynamic addresses. The number of end systems: If there are more than 30 end systems, dynamic address assignment is preferred. Static assignment can be used for smaller networks.

How are addresses assigned to new devices during DHCP?
