What Is DHCP Example?


Why is 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.

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.

Where is DHCP used?

DHCP (Dynamic Host Configuration Protocol) is a protocol that provides quick, automatic, and central management for the distribution of IP addresses within a network. DHCP is also used to configure the subnet mask, default gateway, and DNS server information on the device.

What is DHCP explain?

Overview. Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers (that is, a scope) configured for a given network.

Should I disable DHCP?

We may disable DHCP and configuring a static IP on each device is a significant step in the process of ensuring your security. Generally the only reason one disables DHCP is if there is a chance for misbehavior.

What is DHCP lookup failed?

Troubleshooting Your DHCP Lookup Error. If you receive the message DHCP Lookup Error, this is means that an IP address has not been assigned to your device and you will be unable to access the network. The first thing you should do, as mentioned, is to make sure that DHCP has been enabled on your server.


The DHCP employs a connectionless service model, using the User Datagram Protocol (UDP). It is implemented with two UDP port numbers for its operations which are the same as for the BOOTP protocol. UDP port number 67 is the destination port of a server, and UDP port number 68 is used by the client.

Does DHCP use TCP or UDP?

Why does DHCP use UDP and not TCP? DHCP uses UDP as its transport protocol. DHCP messages that a client sends to a server are sent to well-known port 67 (UDP—Bootstrap Protocol and DHCP).

Is DNS a protocol?

(Although many people think “DNS” stands for “Domain Name Server,” it really stands for “Domain Name System.”) DNS is a protocol within the set of standards for how computers exchange data on the internet and on many private networks, known as the TCP/IP protocol suite.

What is DHCP vs static IP?

A Static IP address is a dedicated IP address that has been assigned to you. DHCP or Dynamic is an IP address that will automatically be chosen for you from a pool of IP addresses that are assigned in the DHCP scope available on your network. Think Static as permanent and DHCP as temporary.
