What is DHCP and how does it work?

Question

Accepted Answer

DHCP automates IP address assignment, enabling devices to connect to networks without manual configuration.

DHCP stands for Dynamic Host Configuration Protocol.
It operates on a client-server model where the DHCP server assigns IP addresses to clients.
The process involves four main steps: Discover, Offer, Request, and Acknowledge (DORA).
Example: A device connects to a network and sends a DHCP Discover message.
The DHCP server responds with a DHCP Offer containing an available IP address.
The client then sends a DHCP Request to accept the offered IP address.
Finally, the server sends a DHCP Acknowledge to confirm the assignment.

Accepted Answer

Dynamic Host Configuration Protocol, Play major role in
Connection of client and server. 
DHCP Server : will assign IP to client 
Client : may be laptop, mobile or any Wifi Devices etc.
main thing is DORA should complete successfully.

Accepted Answer

DHCP stands for Dynamic Host Configuration Protocol. It's a network protocol that automatically assigns IP addresses and other network configuration information to devices on a network. Here's how it works:

Request for IP Address: When a device (like a computer, smartphone, or printer) connects to a network, it sends out a DHCP request to find an available IP address.
DHCP Server: A DHCP server on the network receives these requests. This server manages a pool of available IP addresses and other network settings.
IP Address Assignment: The DHCP server responds to the device's request by assigning it an IP address from the available pool. It also provides additional network configuration details, such as the subnet mask, default gateway (router), and DNS server addresses.
Lease Time: The DHCP server usually assigns IP addresses for a specific period, known as the lease time. After this time expires, the device may request a renewal of its IP address lease.
Renewal and Release: During operation, devices can renew their IP address leases if they remain connected to the network. When a device disconnects or leaves the network, it sends a DHCP release message to inform the server that it no longer needs the assigned IP address.
Dynamic Configuration: DHCP allows for dynamic configuration of IP addresses, which means that devices can join and leave the network without requiring manual configuration of IP addresses on each device. This is particularly useful in large networks where managing IP addresses manually would be impractical.

Accepted Answer

A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients.

Accepted Answer

Dynamic host configuration protocol (DHCP) provides dynamic or automatic ip address assignment. Ip address, subnet mask, default gateway and dns server ip address are assigned automatically by DHCP server. It saves time and hard work.
