What is DHCP? | How to Enable DHCP on Windows 10?

It is very easy to enable DHCP on Windows 10. With DHCP, a computer on the network receives the necessary TCP/IP information from a server or router. If you try to manually configure TCP/IP information for all computers on the network, it is advisable to use DHCP as you will need a lot of time.

After you configure a DHCP server in your network structure, you can automatically assign TCP/IP settings to all computers. If your network has devices with WiFi hardware, these devices will also automatically receive TCP/IP information from your DHCP server.

A DHCP server-enabled server or router cannot assign an IP address on a computer that had been configured a Static IP address on the network.

All devices on the same network will be able to access the IP address pool that you have configured on your ADSL Router or on a local DHCP server. However, you must enable the DHCP service on these devices.

For example, in this article, we’ll enable DHCP on the Windows 10 computer to get an automatic IP address from the ADSL Router.

How DHCP Works?

Let us briefly explain how DHCP works on the network. The DHCP service uses 4 packet requests. These; DHCP Discover, DHCP Offer, DHCP Request, and DHCP ACK.

These packages are required to configure TCP/IP information between DHCP Server and DHCP Client.

DHCP Discover

A new computer joining the network sends a DHCP Discover message to find out the DHCP server. After the computer has found the DHCP Server, the DHCP Offer task starts.

DHCP Offer

After the DHCP Server on the network receives the DHCP Discover package, it sends a DHCP Offer packet to the client to send an IP address.

DHCP Request

The computer sending the DHCP offer message will send a DHCP request message to the DHCP server again. The computer informs you that you have confirmed the IP address with this message. In summary, it accepts IP address.

DHCP ACK

The DHCP Server receives the DHCP Request package and sends the DHCP ACK packet to assign the TCP/IP information to the client and completes it.

What Happens When DHCP is Disabled?

As you can see, it is very easy to enable DHCP on Windows 10. The DHCP settings must be configured correctly. When the DHCP server is disabled, computers on the network cannot automatically obtain an IP address. If there are 150-200 computers in a network environment, the DHCP server must be enabled. Otherwise, you must configure the IP address and other information manually.

If DHCP is off, you must configure TCP/IP manually. In the above steps, you can examine the IP address, Subnet Mask, Gateway, and DNS IP addresses assigned to a computer. If DHCP is turned off in a networked environment with 200 computers, computers cannot receive TCP/IP information and communicate with each other.
