Advantages All the IP configuration information gets automatically configured for your client machine by the DHCP server. If you move your client machine to a different subnet, the client will send out its discover message at boot time and work as usual. However, when you first boot up there you will not be able to get back the IP address you had at your previous location regardless of how little time has passed. Disadvantage Your machine name does not change when you get a new IP address. The DNS (Domain Name System) name is associated with your IP address and therefore does change. This only presents a problem if other clients try to access your machine by its DNS name.

 DHCP is dynamic host configuratio protocol. It is assing  automatic ip address to client machine. Advantage :- It minimize the administrative burden. By using DHCP there is no chance to conflict ip address. DHCP support multiple scope like Unicast,multicast and superscope. By using DHCP relay agent u r provide ip address to another network.Disadvntage :- When client make query to DHCP server (DHCP Discover) it is UDP query it consume more bandwidth. When DHCP server is unavaliable client unable to access entrprises network.

Dynamically configures the IP addresses for the systems present in the network within the specified range only. Reservation of IP address in done here. makes administration at a single point. IP conflict doesnot occurs here.
if some new system comes in to that network, we cannot find the space for the new system in the range specified for the DHCP
