What Is DHCP? and How is it work? Full Details



DHCP


With the increasing number of desktops in a network, the task of assigning and managing ip addresses manually  becomes difficult and prone to errors.Manual Configuration of IP addresses can also result in allocation of invalid IP addresses.

Consider a rapidly developing organization where:




  • All New computers need to be assigned valid IP address.
  • computers are being frequently added to the network.
  • IP addresses should not be duplicated over the network.
  • IP addresses of some computer need to reconfigured because these computers are being transferred from one network to another network .



It is difficult to manage all these tasks manually.

To solve the problem associated with manual assignment of ip addresses,You can implement a DHCP server to assign an IP addresses. the DHCP service will dynamically assign new IP addresses to computers and will release and reconfigure the existing IP addresses. The use of a DHCP server will also resolve the issue of IP addresses duplication. Moreover,It will be Possible to centrally manage the assignment of subnet mask to a Network.therefore,all the time-consuming and error-prone network administration tasks can be efficiently performed using a DHCP server.


therefore,DHCP is an IP standard that simplifies the process of assigning IP addresses to desktops in an organizational network. It helps Dynamically assign IP addresses to all the desktops that are connected in a network. DHCP uses a Client/server model.


Working of DHCP



A DHCP server allocates an IP address to its client dynamically for a limited lease period.The lease is the duration for which an IP address remains valid for a client.The default lease duration is eight days.However,you can increase or decrease this duration on a DHCP Server
