DHCP

Tuesday, February 16, 2016 Posted by Sandeep Kumar Jha

DHCP, Dynamic Host Configuration Protocol, is a communications protocol that dynamically assigns unique IP addresses to network devices.

Here is how the DHCP process works

1. During the boot process, a client computer that is configured as a DHCP
    client sends out a broadcast packet called DHCPDISCOVER.

2. DHCP servers on the network respond to the broadcast with a
    DHCPOFFER.

3. The client responds via a broadcast message called a DHCPREQUEST.
    this message basically says, "I accept your lease offer and would like an IP
    address.

4. The DHCP server whose offer was accepted responds with a DHCPACK
    message, which acknowledges the lease acceptance and contains the
    client's IP address lease.
