Network Protocols Glossary

What is a network protocol? Protocols are the rules of the road for how data exists and moves on the network. They allow many different systems and computers to communicate.

Dynamic Host Configuration (DHCP) Protocol

What is Dynamic Host Configuration (DHCP) Protocol?

DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. This eliminates the need for manual configuration, making network management easier and more efficient.


What is the purpose of DHCP

DHCP Discover: A device that needs an IP address sends a DHCP Discover message to the network.

DHCP Offer: A DHCP server receives the Discover message and responds with a DHCP Offer message, proposing an IP address and other configuration parameters.

DHCP Request: The device selects an offer and sends a DHCP Request message to accept the configuration.

DHCP Ack: The DHCP server responds with a DHCP Ack message, confirming the assignment of the IP address and other parameters.
