portability of workstations
Yes
The benefit would be to automatically assign network addresses to clients that need them to work on a local area network. Without DHCP you would have to assign each device an address, subnet mask, and default gateway, plus DNS and WINS server addresses, which can be time consuming and error prone. With DHCP, most of those problems disappear.
The port 67 and port 68 are used by DHCP and the DHCP clients.
dhcp has to be authorized
The use of a DHCP relay agent is an agent that relays DHCP between DHCP clients and DHCP servers on different IP networks. The DHCP relay agent is compliant with RFC 1542.
router (config)# ip dhcp servicerouter (dhcp-config)# ip dhcp pool router (dhcp-config)# network
(DHCP) Dynamic host Configuration Protocol. The Default Port Number is: for DHCP client : 546 for DHCP server : 547
yes DHCP require the authorization of the dhcp server before IP addresses can be allocated because until we authorize DHCP server the network does not know who is the dhcp server for the subnet. The DHCP server broadcasts the information to all.
This reduces the amount of configuration required for every individual computer.

Those are the four phases of acquiring an IP address via DHCP. More information would be needed to indicate which of the 4 phases are being used at this point.
