What is DHCP?

Introduction: •DHCP is the short form of Dynamic host Configuration Protocol.•It works based on customer server architecture. There room DHCP servers and DHCP clients.•DHCP clients send inquiry to DHCP server when it opens the internet browser.Upon receiving the request, DHCP server replies the info to the requestedDHCP client.•Function: it assigns IP addresses to requesting hosts or client dynamicallyon demand basis.•It uses UDP harbor number 67 as location server and port number 68 forclient.


DHCP protocol runs over UDP and it is characterized in RFC 2131.It helps in configuration of hosts to attain IP addresses automatically in TCP/IPproperties that NIC configuration window.Refer DNS matches DHCP >>.

Benefits or benefits of DHCP

Following room the services or benefits of DHCP:➨DHCP is simple to implement and also does automatically assignment of IP addresses torequesting clients.Hence hand-operated configuration time the IP addresses deserve to be reduced. ➨The implementation walk not call for any additional costs. ➨Duplicate or invalid assignment that IP addresses room prevented.Hence there is no possibility of conflicts in IP addresses. ➨It simplifies administration of the network. ➨It support multiple scopes e.g. Multicast scope, super scope etc. ➨It has an excellent benefit to mobile users as valid configurationparameters are immediately obtained native the new network.

Drawbacks or disadvantages of DHCP

Following are the disadvantages of DHCP:➨DHCP server have the right to be solitary point of failure in networks having only oneconfigured DHCP server. ➨DHCP packets have the right to not travel throughout router, therefore relay agent is necessary tohave DHCP server handle all leases on both network segments. Relay agentsreceive broadcast DHCP packets and also forward them as unicast packets toDHCP server. Here relay agent should be configured through IP deal with of the DHCP server. ➨Security: as DHCP server has actually no secure device for authentication ofthe client, the can acquire unauthorized accessibility to IP addresses by presenting credentialssuch as customer identifiers i m sorry belong to other DHCP clients. ➨The machine name walk not readjust when brand-new IP address is assigned. ➨Client is no able to access the network in the absence of the DHCP server.
