Introduction
Today, we are covering “What is DHCP and How It Works” This tutorial will cover everything about DHCP servers. DHCP stands for (dynamic host configuration Protocols) and is a network protocol for managing large numbers and providing client devices IP addresses automatically and other network parameters resources like subnet mask, DNS IP address, and default gateway.
DHCP server works on some factors like Discovery, Offer, Request, Acknowledgment, renewal, release, etc. All these topics will be covered in the article. Following the process, the DHCP server releases the IP address for the client as per the requirement of client devices set up for a specific period. this message also includes the lease duration and configuration parameters. I hope you understand some basics about the DHCP server.
What is a DHCP Server?
DHCP stands for dynamic host configuration protocol) a network management server protocol automatically provides all network perimeters like IP, subnet mask, default gateway, and network resources to client devices. For Example, if more than 1000 thousand devices are in the organization not possible to assign IP addresses manually on each device.
So in this scenario, DHCP plays a big role in assigning IP addresses automatically on each client device. When connecting a client device and sending a request to the DHCP server for an IP address that releases IP for client devices that role-play the DHCP server.
Why is DHCP Used?
It’s not passable to manage a large number of networks in an organization. So DHCP server plays a big role in helping manage the entire process automatically and centrally. There are several reasons to use DHCP.
1. Network management- DHCP easily manages network resource administration by centralizing the management of IP address assignments. Network administration can configure the DHCP network server and allocate IP addresses from a pool, ensuring the utilization of all resources of available addresses.
2. Assign automatically IP Address- As already discussed it is not possible to manage to large number of networks that can not assign IP addresses manually static IP on each device on the network. DHCP makes it easy to automate this process. The DHCP process saves time and reduces the risk to human
3. Manage Centralized configuration- Once enabled DHCP server is made easy to centralize the configuration of network parameters such as subnet masks, default gateways, and DNS server address.
4. IP address conflicts reduced- Sometimes if IP addresses are manually to multiple devices, attempt to use the IP address conflict issue. So DHCP server is reduced to IP address infliction.
How Does a DHCP Work?
Here are some steps to DHCP work a series
1. DHCP Discovery- When connecting devices to the network, it sends a message to broadcast that process called a DHCP to discover packet. When the client device sends a packet broadcast to ask “Is there a DHCP server out there that can give me an IP address?” for this client device.
2. DHCP Offer- When receiving DHCP the discovers packet from the client device, Then the DHCP server sends one offer packet to the client device. That packet is an IP address packet released by the DHCP server for the client device as per the requesting device. This process called is a DHCP offer.
3. DHCP Request- Once Receiving packet offer which is sent from the DHCP server to the client device. Then client devices send formal requests for the offered IP address from the DHCP server.
4. DHCP Acknowledgment- When the DHCP server receives the request packet that is sent by the request device. DHCP server lease by sending acknowledgment packet to requesting device. This packet fixes the IP address assignment including the subnet mask, default getaway, and network parameter other with the duration of the lease which specifies how long can the device use the assigned IP address before needing to renew it. That process is called the DHCP acknowledgment process.
5. IP Address Lease- Now received one IP address and other network configuration parameters for the requested device from the DHCP server now ready allowing it to communicate on the network. Now the device can use this IP address for the duration of the lease period.
6. Lease Renewal- When the DHCP server releases the IP address on the client devices fix a specific time for renewal once the time duration of lease renewal so client devices send a request to the DHCP server for renewal that process is known as lease renewal.
What are the Key Features of the Dynamic Host Configuration Protocol (DHCP)?
1. Automatic IP address Assignment- DHCP servers assign IP addresses automatically on the client devices and do not require IP addresses on the devices to manually. It helps to assign easy setup network configuration in the large area network.
2. Dynamic IP address Allocation- DHCP server support allows IP address requested devices dynamically in the network to receive temporary addresses from the pool maintained by the DHCP server. DHCP server optimizes the usable IP address and accommodates devices joining and leaving the network.
3. IP address lease management- DHCP server releases IP address to requested devices specified period it is known as lease duration. After the lease period fix one specified expires, Now device must renew its lease to continue using the IP address the IP address. DHCP server lease management ensures to IP address and allows it to be easily used in network configuration.
4. Centralized Configuration- The DHCP server always configures centralization management of network parameters like subnet masks, default gateways, DNS server addresses, and other network parameters. This centralization management makes network management tasks and ensures the stability regularly all connected devices regularly.
5. Reduced IP address Conflicts- If assigned IP addresses in a large network may be passably facing issue conflicts but if assigned dynamically from a centralized pool no chance of IP address conflicts. DHCP server always tracks the IP address of all assignments devices to receive a unique address to avoid conflicts.
Conclusion
In this tutorial learn about DHCP Server, You have learned the steps following the DHCP server to assign an IP address to a client device in the network to help devices communicate with worldly connect Then, you also talked about the steps involved in assigning an IP address process between client and DHCP Server. I hope! now you understand the DHCP server which processes the following to provide IP addresses to client devices and help full for you.
DHCP Server is a network protocol that makes it easy to manage a large number of networks in the organization. It works through a series of message exchanges between the DHCP server and client devices to stability for connecting worldly. DHCP Server process ensures stability and flexible network management, allowing devices to connect smoothly and communicate on the network without manual configuration.
