How DHCP Works:-
What is DHCP?
Dynamic Host Configuration Protocol (DHCP) is a system convention that empowers a server to naturally relegate an IP deliver to a PC from a characterized scope of numbers (i.e., an extension) arranged for a given system.
How DHCP gives IP addresses
DHCP allows an IP address when a framework is begun, for instance:
A client turns on a PC with a DHCP customer.
The customer PC sends a communicate ask for (called a DISCOVER or DHCPDISCOVER), searching for a DHCP server to reply.
The switch guides the DISCOVER bundle to the right DHCP server.
The server gets the DISCOVER bundle. In view of accessibility and use arrangements set on the server, the server decides a fitting location (assuming any) to provide for the customer. The server at that point incidentally holds that address for the customer and sends back to the customer an OFFER (or DHCPOFFER) bundle, with that address data. The server additionally arranges the customer’s DNS servers, WINS servers, NTP servers, and now and again different administrations too.
The customer sends a REQUEST (or DHCPREQUEST) parcel, telling the server that it means to utilize the address.
The server sends an ACK (or DHCPACK) bundle, affirming that the customer has a been given a rent on the address for a server-determined timeframe.

Static IP addresses
At the point when a PC utilizes a static IP address, it implies that the PC is physically designed to utilize a particular IP address. One issue with the static task, which can come about because of client blunder or absentmindedness to detail, happens when two PCs are designed with a similar IP address. This makes a contention that outcomes in loss of administration. Utilizing DHCP to progressively appoint IP addresses limits these contentions.
