Dynamic Host Configuration Protocol (DHCP) is a network protocol that is used to configure network devices to communicate on an IP network. A DHCP client uses the DHCP protocol to acquire configuration information, such as an IP address, a default route, and one or more DNS server addresses from a DHCP server.
What is DHCP in simple words?
DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to dynamically assign an IP address to any device, or node, on a network so it can communicate using IP.

What is DHCP and DNS?
Domain Name System (DNS) is an Internet service that translates domain names (e.g., its.umich.edu) into IP addresses. Dynamic Host Configuration Protocol (DHCP) is a protocol for automatically assigning IP addresses and other configurations to devices when they connect to a network.

What is DHCP and how does it work?
A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients.

When should DHCP be used?
So, do you need a static IP or a DHCP IP address? The answer is simple. If no one on your tech team specifically told you that they require a static IP address, you probably don't need one. In other words, if you just need to plug your computer, printer, smart device, etc., into the switch, you need DHCP.

Where is DHCP defined?
RFCs 2131 and 2132 define DHCP as an Internet Engineering Task Force (IETF) standard based on Bootstrap Protocol (BOOTP), a protocol with which DHCP shares many implementation details. DHCP allows hosts to obtain required TCP/IP configuration information from a DHCP server.

What happens when you disable DHCP?
If you turn off DHCP, you'll have to manually configure each connected device and assign it an IP address. This is more time-consuming but considered to be safer. For more useful info on networking, check out our guide to converting an older router into an access point and turning off the WiFi on a router.

What should my DHCP settings be?
Since the default DHCP address range is between 100 and 149, you'll want to avoid all of the addresses between 192.168. 1.100 and 192.168. 1.149 when you're assigning static IP addresses. That leaves the ranges from 2-99 and from 150-254 wide open, which is usually plenty for most home networks.

What will happen if DHCP is enabled?
DHCP is used to automatically get an IP address from your router. If you've turned it off, you need to set a static IP address, as well as a Subnetmask and default gateway on your client PC. The IP address needs to be in the same subnet as your router.

Do you need DHCP for WIFI?
Short answer: No, a wifi AP does not have to take care of DHCP and DNS too. Furthermore, they have to support disabling those services, as often you can have more than one in one location/network.

How does DHCP and DNS work together?
If configured to make DNS updates, the DHCP server attempts to update DNS with the client's suggested host name. If the DNS update is successful, the DHCP server returns the requested host name to the client. If the DNS update is not successful, the DHCP server returns a different host name to the client.

What is DNS used for?
