Some of the disadvantages of the centralized network is that it is complex to computation. The other disadvantage is that a single point failure may affect the entire network.
The port 67 and port 68 are used by DHCP and the DHCP clients.
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.

They use DHCP to assign IP Addresses to Devices such as Windows XP, Networking flashcards, OIt DHCP and BootP services, and connecting routers. The definition for DHCP is Dynamic Host Configuration Protocol.
dhcpnack is message from dhcp server when dhcp server is not having any ip left in address pool or client fails to respond to offer in given time
Infrastructure Services
Active Directory is commonly used for this.
Advantages:Clients have ready access to their DHCP servers.All client/server traffic is local.There is no worry about DHCP traffic adding to the burden of routers.
While the weakness or lack of centralized curriculum development can be seen from any aspects. One disadvantage of this centralized system is quite large areas have diversity in the conditions, needs and level of progress, a national curriculum can not accommodate the diversity of the condition.
DHCP s just a server that provides IP details to a computer. Since it can be set up to give statc IP address details to specific computers it has no disadvantage....unless of course the DHCP server crashes.
With centralized data processing, one advantage is that you can control all the processing for your business from one location. If you're working on a terminal and it goes down, you can log into another one and keep working. On the other hand, if the central computer goes down, no work can be done on any of the terminals. This is the biggest disadvantage.
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
Centralized processing makes it easier to maintain security and standards in addition to making duplication less likely. The biggest disadvantage of centralized processing is that if the system goes down, then all systems may be inaccessible.
(DHCP) Dynamic host Configuration Protocol. The Default Port Number is: for DHCP client : 546 for DHCP server : 547
