What is the principal of DHCP server to?

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.

How DHCP server works step by step?

How do DHCP works? DHCP works at the application layer to dynamically assign the IP address to the client and this happens through the exchange of a series of messages called DHCP transactions or DHCP conversation. DHCP Discovery: The DHCP client broadcast messages to discover the DHCP servers.

How does the DHCP works?

DHCP works by leasing IP addresses and IP information to network clients for a period of time. For the lease to happen, the following negotiation process occurs: 1. This Discover packet contains the client’s computer name and Media Access Control (MAC) address so the DHCP servers can respond to it.

How does DHCP server work explained with examples?

When it receives a DHCP request from a DHCP client, it provides an IP configuration to the client from all available IP configurations. This entire process goes through the four steps: Discover, Offer, Request, and Acknowledgment. In this tutorial, we will understand these four steps in detail.

How does the DHCP server set the destination address?

In reply to the DHCPDISCOVER message, a DHCP server sends a DHCPOFFER message to the client. Since the client does not have an IP address, the DHCP server cannot send the DHCPOFFER message directly to the client. Because of this, the server sets the destination address to 255.255.255.255.

How does the DHCP server lease an IP?

The DHCP server broadcasts this message to lease an IP configuration to the DHCP client. The DHCP client uses this message to notify the DHCP server whether it accepts the proposed IP configuration or not. The DHCP server uses this message to confirm the DHCP client that it can use the offered IP configuration.

What is the source IP address for a DHCP message?

1. DHCPDISCOVER It is a DHCP message that marks the beginning of a DHCP interaction between client and server. This message is sent by a client (host or device connected to a network) that is connected to a local subnet. It’s a broadcast message that uses 255.255.255.255 as destination IP address while the source IP address is 0.0.0.0
