Stands for “Dynamic Host Configuration Protocol.” DHCP is a protocol that automatically assigns a unique IP address to each device that connects to a network.
With DHCP, there is no need to manually assign IP addresses to new devices.
What is DHCP and why it is used?
Dynamic Host Configuration Protocol (DHCP) is a network management protocol used to automate the process of configuring devices on IP networks, thus allowing them to use network services such as DNS, NTP, and any communication protocol based on UDP or TCP. DHCP is an enhancement of an older protocol called BOOTP.
What are the 4 steps of DHCP?
DHCP operations fall into four phases: server discovery, IP lease offer, IP lease request, and IP lease acknowledgement. These stages are often abbreviated as DORA for discovery, offer, request, and acknowledgement.
Why is a DHCP important?
DHCP allows you to manage the networks’ IP addresses scopes and other TCP/IP settings like DNS, Default Gateway, etc. from central place, this central place called DHCP server. You can provide to your clients IP addresses from the selected range that you’ve configured and some other TCP/IP options.
