Below are the steps how DHCP Client/Server relationship works.

  • IN the network the clicent device requests a packets to DHCP server to login to the network. This Packet known as DHCPDiscover.
  • The DHCP Server receives that packet and in responce it sends a packet to the client, this is called as DHCPOffer. This DHCPOffer packet contains unleased or unused list of IP(internet Protocol) addresses over the LAN.
  • The DHCP Client receives the DHCPOffer from DHCP Server and responds. This is called DHCPRequest, and this request contains the accepted IP address in the DHCPOffer it received from DHCP Server.
  • Now the DHCP Server receives the DHCPRequest and sends back the DHCPPackets and lets clients to access network.

Leases are retained in the DHCP server database four hours after expiration. This grace period protects a client lease in case the client and server are in different time zones, the individual computer clocks are not synchronized, or the client computer is off the network when the lease expires. Expired leases are included in the list of active leases and are distinguished by a different icon.

What is Dora process in DHCP and how it works?

1) Client makes a UDP Broadcast to the server with a DHCPDiscover, or Discover packet. 2) DHCP offers to the client. The server sends a DHCPOffer including other configuration parameters (DHCP Options) for the client per the servers configuration file 3) In response to the offer Client requests the server. The client replies DHCPRequest, unicast to the server, requesting the offered address. 4)The server sends DHCPAck acknowledging the request which is the clients final permission to take the address as offered. Before sending the ack the server double checks that the offered address is still available, that the parameters match the clients request and (if so) marks the address taken. A good reference for DHCP information is Droms and Lemon "The DHCP Handbook". BoydK
