what are the advanteges and disandvanges of using DHCP surver

➨DHCP is easy to implement and does automatic assignment of IP addresses to requesting clients. Hence manual configuration time of IP addresses can be reduced.

➨The implementation does not require any additional costs.

➨Duplicate or invalid assignment of IP addresses are prevented. Hence there is no chance of conflicts in IP addresses.

➨It simplifies administration of the network.

➨It supports multiple scopes e.g. multicast scope, super scope etc.

➨It has great benefit to mobile users as valid configuration parameters are automatically obtained from the new network.

Explanation:

disadvantages of DHCP:

➨DHCP server can be single point of failure in networks having only one configured DHCP server.

➨DHCP packets can not travel across router, Hence relay agent is necessary to have DHCP server handle all leases on both network segments. Relay agents receive broadcast DHCP packets and forward them as unicast packets to DHCP server. Here relay agent must be configured with IP address of the DHCP server.

➨Security: As DHCP server has no secure mechanism for authentication of the client, it can gain unauthorized access to IP addresses by presenting credentials such as client identifiers which belong to other DHCP clients.

➨The machine name does not change when new IP address is assigned.

➨Client is not able to access the network in the absence of the DHCP server.
