DHCP helps in managing the entire process automatically and centrally. DHCP helps in maintaining a unique IP Address for a host using the server. DHCP servers maintain information on TCP/IP configuration and provide configuration of address to DHCP-enabled clients in the form of a lease offer. Components of DHCP The main components of DHCP include: • DHCP Server: DHCP Server is basically a server that holds IP Addresses and other information related to configuration. • DHCP Client: It is basically a device that receives configuration information from the server. It can be a mobile, laptop, computer, or any other electronic device that requires a connection. • DHCP Relay: DHCP relays basically work as a communication channel between DHCP Client and Server. • IP Address Pool: It is the pool or container of IP Addresses possessed by the DHCP Server. It has a range of addresses that can be allocated to devices. • Subnets: Subnets are smaller portions of the IP network partitioned to keep networks under control. • Lease: It is simply the time that how long the information received from the server is valid, in case of expiration of the lease, the tenant must have to re-assign the lease. • DNS Servers: DHCP servers can also prov...

History DHCP was used for the first time in 1993. It was built on the Bootstrap Protocol (BOOTP) of 1985. The definition of the Dynamic Host Configuration Protocol is in RFC 2131 and can be found under the UDP port numbers 67 and 68. Basic Functioning Upon dynamically configuring a device with dynamic IP from a DHCP server, three things come into play, the IP address (of course), subnet mask and the default gateway. Configuring a DHCP server to hand out IP addresses on a subnet is known as a DHCP pool. This pool of addresses is usually a range of consecutive numbers within a single IP subnet. If any of the addresses within the range needs to be blocked, it can be done by the administrator. The subnet mask tells devices how large the subnetwork is that they are connected to; this is critical from a broadcast perspective. Finally, the default gateway is the IP address that signifies the exit point of the subnetwork to which the device belongs. Characteristics • Centralized and automated TCP/IP configuration. • The efficient handling of IP address changes for clients that must be updated frequently, such as those for portable devices that move to different locations on a wireless network. • The forwarding of initial DHCP messages by using a DHCP relay agent, which eliminates the need for a DHCP server on every subnet. • The ability to define TCP/IP configurations from a central location. DHCP Lease Time In most cases, DHCP will work with default settings that largely are the ...

DHCP Can Handle IP Assignments Every device that connects to a network needs an IP address. In the early days of networking, users manually assigned themselves an IP address, but that’s a cumbersome task, especially for places with many devices, such as a corporate office. DHCP, in part, automates this process, which makes connecting devices to the network far easier. DHCP servers or routers handle this process based on a set of defined rules. Most routers are set to use a 192.168.0.x range, for instance, so you’ll commonly see IP addresses like this in home networks. The process is pretty straight forward. When a client (a computer, IOT device, tablet, cell phone, etc.) connects to the network, it sends out a signal (called DHCPDISCOVER) to the DHCP server (or router). The server responds with all the rules and settings for the network and an IP address for use (a DHCPOFFER). The client acknowledges the information and asks permission to use the assigned address (a DHCPREQUEST message). Finally, the DHCP server acknowledges the request, and the client is free to connect to the network. DHCP Controls the Range of IP Addresses You can c...

By • Technical Writer and Editor What is DHCP (Dynamic Host Configuration Protocol)? DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to dynamically assign an IP address to any device, or DHCP assigns new IP addresses in each location when devices are moved from place to place, which means network administrators do not have to manually configure each device with a valid IP address or reconfigure the device with a new IP address if it moves to a new location on the network. Versions of DHCP are available for use in IP version 4 ( How DHCP works DHCP runs at the application layer of the DHCP is a client-server protocol in which servers manage a pool of unique IP addresses, as well as information about client configuration parameters. The servers then assign addresses out of those address pools. DHCP-enabled clients send a request to the DHCP server whenever they connect to a network. Clients configured with DHCP broadcast a request to the DHCP server and request network configuration information for the local network to which they're attached. A client typically broadcasts a query for this information immediately after booting up. The DHCP server responds to the client request by providing IP configuration information previously specified by a network administrator. This includes a specific IP address, as well as a time period -- also called a lease-- for which the allocation is valid. When refreshing an address assignment, a DHCP client reque...

Once the offer has been made for the chosen IP address, the device responds to the DHCP server with a DHCPREQUEST packet to accept it. Then, the server sends an ACK to confirm that the device has that specific IP address and to define the amount of time that the device can use the address before getting a new one. Pros and Cons of Using DHCP A computer, or any device that connects to a network (local or internet), must be properly configured to communicate on that network. Since DHCP allows that configuration to happen automatically, it's used in almost every device that connects to a network including computers, Using DHCP makes a network easier to manage. From an administrative point of view, every device on the network can get an IP address with nothing more than their default network settings, which is set up to obtain an address automatically. The alternative is to manually assign addresses to each device on the network. In most cases, when a device has an IP address assigned by a DHCP server, that address changes each time the device joins the network. If IP addresses are assigned manually, administrators must give out a specific address to each new client, and existing addresses that are assigned must be manually unassigned before other devices can use that address. This is time-consuming, and manually configuring each device increases the chance of errors. There are advantages to using DHCP, and there are disadvantages. Dynamic, changing IP addresses should not be ...

In this article Dynamic Host Configuration Protocol (DHCP) is a standard protocol defined by RFC 1541 (which is superseded by RFC 2131) that allows a server to dynamically distribute IP addressing and configuration information to clients. Normally the DHCP server provides the client with at least this basic information: • IP Address • Subnet Mask • Default Gateway Other information can be provided as well, such as Domain Name Service (DNS) server addresses and Windows Internet Name Service (WINS) server addresses. The system administrator configures the DHCP server with the options that are parsed out to the client. More Information The following Microsoft products provide DHCP client functionality: • Windows NT Server versions 3.5, 3.51, and 4.0 • Windows NT Workstation versions 3.5, 3.51, and 4.0 • Windows 95 • Microsoft Network Client version 3.0 for MS-DOS • Microsoft LAN Manager Client version 2.2c for MS-DOS • Microsoft TCP/IP-32 for Windows for Workgroups versions 3.11, 3.11a, and 3.11b Different DHCP clients support different options that they can receive from the DHCP server. The following Microsoft server operating systems provide DHCP server functionality: • Windows NT Server version 3.5 • Windows NT Server version 3.51 • Windows NT Server version 4.0 When a client is initialized for the first time after it is configured to receive DHCP information, it initiates a conversation with the server. Below is a summary table of the conversation between client and serve...

Initialism What does DHCP mean? Dynamic Host Configuration Protocol ( DHCP) is a network protocol that automatically assigns an Internet Protocol (IP) address and other related configuration information such as the default gateway and subnet mask to a network device within the network.
