          DHCP
            It gives IP Addresses Automatically to the Clients who is requesting for an IP Address
            Centralized IP Address Management
            DHCP prevents IP address Conflicts and helps conserve the use of client IP Address on the Network
            DHCP reduces the complexity and amount of administrative work by assigning TCP/IP configuration
            Client IP configuration is updated automatically

          Why DHCP?
           Static IP Assigning                           Dynamic IP Assigning
             IP addresses are entered manually            IP addresses are supplied automatically
             IP address could be entered incorrectly      Correct configuration information is ensuring
             Communication and network issues can         Client configuration is updated automatically
              result                                       A common source of network problems is
             Frequent computer moves increase                eliminated
              administrative effort

          Process of IP Assignment by DHCP:
             1.  When a client computer starts, if it is configured to use DHCP Server to get IP address.
             2.  Client Computer sends a DISCOVER broadcast request on network.
             3.  DHCP server received this request and sends an OFFER packet back to client.
             4.  After getting offer packet, Client sends a REQUEST packet to DHCP server to assign an IP.
             5.  DHCP Server assigned the IP to client computer and sends a ACK packet to client.
