What is DHCP Server ?
DHCP (Dynamic Host Configuration Protocol) is a network protocol that enables a server to automatically assign an IP address and provide other related network configuration parameters to a client on a network, from a pre-defined IP pool.
This means that each time a client (connected to the network) boots up, it gets a “dynamic” IP address, as opposed to “static” IP address that never changes. The IP address assigned by a DHCP server to DHCP client is on a “lease”, the lease time can vary depending on how long a client is likely to require the connection or DHCP configuration.
In this tutorial, we will cover how to install and configure a DHCP server in CentOS/RHEL and Fedora distributions.
Testing Environment Setup
We are going to use following testing environment for this setup.
DHCP Server - CentOS 7
DHCP Clients - Centos 7 and Windows 10
How Does DHCP Work?
Before we move any further, let’s briefly explain how DHCP works:
When a client computer (configured to use DHCP) and connected to a network is powered on, it forwards a DHCPDISCOVER message to the DHCP server.
And after the DHCP server receives the DHCPDISCOVER request message, it replies with a DHCPOFFER message.
Then the client receives the DHCPOFFER message, and it sends a DHCPREQUEST message to the server indicating, it is prepared to get the network configuration offered in the DHCPOFFER message.
Last but not least, the DHCP server receives the DHCPREQUEST message from the client, and sends the DHCPACK message showing that the client is now permitted to use the IP address assigned to it.

Hi All,
I configured DHCP Server in the CentOS7 machine and the range I took was 192.168.0.50 to 192.168.0.125.
It works when I tried from two CentOS 6.4 machines.
One of them got an IP of 192.168.0.50 and the other got 192.168.0.53.
When I am trying from a CentOS7 client , the IP it gets is 192.168.0.10
I have changed the bootproto to dhcp and onboot to yes .
So just wondering why it did not get the IP of the DHCP Server range.
Please help.
how can i go from username@localhost to root@server in linux centOS ??
Guide me please from command.
Great
thank you ok

hello are your settings made for virtual machines?
or for a local network
just as they told me that when configuring DHCP, 2 physical adapters are needed
Hello Sir, I have configured the way you explained. However, DHCP is not assigning the IP from the range which I have configured in dhcpd.conf file. It is assigning randomly.
Plz help.
