What happens in DHCP Explain Dora process in detail What is vlan

Question

Accepted Answer

DHCP is a network protocol that allows devices to obtain IP addresses and other network configuration settings automatically.

DHCP stands for Dynamic Host Configuration Protocol.
It is used to assign IP addresses dynamically to devices on a network.
The DORA process in DHCP stands for Discover, Offer, Request, and Acknowledge.
During the DORA process, a client sends a DHCP Discover message to find available DHCP servers.
The DHCP server responds with a DHCP Offer message, providing an IP address and other configuration options.
The client then sends a DHCP Request message to request the offered IP address.
Finally, the DHCP server sends a DHCP Acknowledge message to confirm the IP address assignment.
VLAN stands for Virtual Local Area Network.
It is a logical grouping of devices on a network, allowing them to communicate as if they were on the same physical network.
VLANs provide network segmentation, security, and flexibility.
For example, a company may have separate VLANs for different departments, such as finance, marketing, and IT.
Devices within a VLAN can communicate with each other directly, while communication between VLANs requires routing.

DHCP is a client-server protocol in which servers manage a pool of unique IP addresses, as well as information about client configuration parameters. The servers then assign addresses out of those address pools. DHCP-enabled clients send a request to the DHCP server whenever they connect to a network.
Broadcast-based DORA (Discover, Offer, Request, Acknowledgement). This process consists of the following steps: The DHCP client sends a DHCP Discover broadcast request to all available DHCP servers within range. A DHCP Offer broadcast response is received from the DHCP server, offering an available IP address lease.
A virtual LAN (VLAN) is a logical overlay network that groups together a subset of devices that share a physical LAN, isolating the traffic for each group. A LAN is a group of computers or other devices in the same place -- e.g., the same building or campus -- that share the same physical network.
