The Dynamic Host Configuration Protocol (DHCP) is an Internet Engineering Task Force (IETF) standard designed to reduce the administration burden and complexity of configuring hosts on a Transmission Control Protocol/Internet Protocol (TCP/IP)-based network.
DHCP is a communications protocol that allows network administrators to manage and automate IP (Internet Protocol) addresses on an organizations network. Using the Internet Protocol, each machine that can connect to the Internet needs a unique IP address, which is assigned when an Internet connection is created for a specific computer. Without DHCP, the IP address must be entered manually at each computer in an organization and a new IP address must be entered each time a computer moves to a new location on the network. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network.
DHCP uses the concept of a "lease" or amount of time that a given IP address will be valid for a computer. The lease time can vary depending on how long a user is likely to require the Internet connection at its location. It's particularly useful in education and other environments where users change regularly. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than there are available IP addresses. The protocol also supports static addresses for computers that need a permanent IP address, such as Web servers.
DHCP is an extension of an earlier network IP management protocol, Bootstrap Protocol (BOOTP). DHCP is a more advanced protocol, but both configuration management protocols are commonly used and DHCP can handle BOOTP client requests. Some organizations use both protocols, but understanding how and when to use them in the same organization

Dhcp

...DHCP DHCP, an acronym for Dynamic Host Configuration Protocol, is a protocol used to automatically assign a unique IP address to a device. DHCP allows a computer to join an IP-based network without having a pre-configured IP address. DHCP is a protocol that assigns unique IP addresses to devices, then releases and renews these addresses as devices leave and re-join the network. DHCP is also used to configure the proper subnet mask, default gateway, and DNS server information on the device. A computer, or any other 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, switches, smartphones, etc. When a computer or other networked device connects to a network, its DHCP client software in the operating system sends a broadcast query requesting necessary information. Any DHCP server on the network may service the request. The DHCP server manages a pool of IP addresses and information about client configuration parameters such as default gateway, domain name, the name servers, and time servers. On receiving a request, the server may respond with specific information for each client, as previously configured by an administrator, or with a specific address and any other information valid for the entire network, and the time period for which the allocation (lease) is valid.

Dhcp Troubleshooting

...DHCP Troubleshooting Each subnet can have only a single DHCP scope with a single continuous range of IP addresses. To use several address ranges within a single scope or subnet for the DHCP service, you must first define the scope and then set any required exclusion ranges. Use the entire range of consecutive IP addresses that make up the local IP subnet for which you are enabling the DHCP service. Set exclusion ranges for any IP addresses within the scope that you do not want the DHCP server to offer or use for DHCP assignment. By setting an exclusion range for these addresses, you specify that DHCP clients are never offered these addresses when they request an IP address from the server. Excluded IP addresses can be active on your network, but only by manually configuring these addresses at hosts that do not use DHCP to obtain an address. To create a new DHCP scope: 1. Open the DHCP Microsoft Management Console (MMC) snap-in. 2. In the console tree, double-click the DHCP server you want to configure. 3. Right-click IPv4 or IPv6 and then click New Scope. 4. Follow the instructions in the New Scope Wizard. Before you create the scope, determine starting and ending IP addresses to be used within it. Depending on the starting and ending IP addresses for your scope, the DHCP console suggests a default subnet mask useful for most networks. If you know a different subnet mask is required for your network, you can modify the value as needed. When you finish creating...

...Javier Dominguez DNS & DHCP DNS allows people to use meaningful names, such as http://www.yahoo.com.proxy.itt-tech.edu, to find Internet-based resources. In this way, DNS has allowed users from a wide range of educational backgrounds to makes use of the Internet. DNS eliminated the need to manually remember IP addresses and replaced that system with human-readable names instead; DNS was invented to solve the logistical problems that arose because too many hosts were on the Internet to be able to keep track of using a manual list of addresses. In other words DNS function is to translate names to IP addresses and vice versa, that way instead of remembering a long IP address you can just type a name that is easy to remember. http://library.books24x7.com.proxy.itt-tech.edu/assetviewer.aspx?bookid=12254&chunkid=309282908&rowid=24 With the increasing number and different types of devices attaching to the network, managing IP addresses efficiently and accurately introduces many challenges for network operators of large-scale networks, including service providers and enterprises. Both Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) are mission-critical capabilities that need to be able to scale, and many service providers have created dynamic service delivery based on DNS to achieve service quality and deliver advantages. However, if DNS fails, then the Internet fails. Assigning a unique address to every device connecting to the network has...

Dhcp Troubleshooting

...Assignment 1. DHCP Troubleshooting Dear Junior Administrator, I would start by rechecking your initial configurations to make sure the setting were saved. Once that is done, check to see if the workstations have picked up a new lease or not. If that doesn’t resolve the issue, did you check to make sure the server is up and operational? Have any Error messages or pop up’s appear with any type of warning, if so what did it say? Once the server has been checked, if it is working properly we will check these three common problems; 1. “The client might be configured to use an IP address not provided by the server. 2. The server sends a negative response back to the client, and the client displays an error message or popup indicating that a DHCP server could not be found. 3. The server leases the client an address but the client appears to have other network configuration–based problems, such as the inability to register or resolve DNS or NetBIOS names, or to perceive computers beyond its same subnet.”(Troubleshooting DHCP) On the chance that the DHCP server is off I would like you to follow these steps to try to restart the DHCP server. 1. “Start Windows Server, and log on under an account with Administrator rights. 2. At the command prompt, type net start dhcpserver , and then press ENTER. As a helpful tool Use Event Viewer in Administrative Tools to find the possible source of problems with DHCP services.”(Troubleshooting DHCP) I hope some of this...

...DHCP Troubleshooting Dear IT Admin: I am working at a branch office and have been tasked with changing out the DHCP scope to match the overall corporate IP address scheme. The main office assigned me an IP address range of 192.168.0.200 through 192.168.0.225. I changed the scope on Friday afternoon and came in on Monday morning to discover that only some of the workstations had picked up new leases from the new DHCP scope. Any ideas as to what may be happening what I might check or adjust? Thank you, Junior Admin From IT Admin: To: Junior Admin: A scope must be defined and activated before DHCP clients can use the DHCP server for dynamic TCP/IP configuration. DHCP servers do not communicate scope information with each other, you must be careful to define scopes so that multiple DHCP servers are not assigning the same IP address to multiple clients or assigning addresses that are statically assigned to existing IP hosts. A DHCP server can only service requests for a scope that has a network ID that is the same as the network ID of its IP address. Use the display dhcp server tree all command to verify that an address pool containing or residing on the same subnet as the subnet of the receiving interface’s IP address is configured. The DHCP server assigns IP addresses with leases (support for lease duration depends on the device model). If an IP address has passed its lease duration, the DHCP server does not assign the IP address. Execute the display dhcp server ip-in-use...

Any ideas as to what may be happening, what I might check or adjust? Thank you, Junior Admin --- Dear Junior Admin, A common problem that happens more often than not is assuming as soon as DHCP options are changed that all PCs will automatically implement them. It sounds like this may be an example of that exactly. With DHCP when the computer comes online it does a broadcast search for a DHCP server. The server responds with a message offering an IP address, subnet mask, and default gateway as well as some DNS options and WINS if that is configured. Once the pc accepts it the DHCP server will send an acknowledgement message. At that point the PC will send back a message that it will take it and the DHCP server will send a message indicating that an IP address has been reserved for the lease period. At this point the PC will not contact the DHCP server again until halfway through the lease time, which is usually a default period of 8 days. If you want to force all of the PCs to grab a new IP address then you will have to go to each computer, open a DOS prompt, and...

What Is Dhcp

...DHCP Working at a company where you have to individually assign IP address to all network devices can be problematic and time consuming. If the IT persons has to assign an IP address to all the devices, then he has to make sure there is no IP conflicts within the network and they are all set up properly so that the information that has to be routed to the correct port and device get there. This process can be done but then again it is very time consuming and the margin for error is higher since you have to pay close attention to your IP tables and keep track what IP range and IP addresses you are assigning out to devices. Now if the use of a router that has DHCP is implemented all the problems for the most part when it comes assigning IP addresses and ranges should be taken care of. With DHCP it’s easier to install new clients because you don’t have to worry about which IP you’re going to give out or if some other device on the network already has been assigned that IP. DHCP also eliminates problems caused by IP address conflicts by never allowing any dive to be outside the IP range or being assigned a used IP address. When a DHCP server receives a request from a client, it chooses an IP address and other related information from a pool of addresses known as a scope and offers it to the client. Certain addresses within the scope may be excluded from distribution because they have already been assigned as static addresses. If the client accepts the address offered, the IP addressing...

Dhcp Reseach

...DHCP Troubleshooting When you log on to the Internet, the ISP uses DHCP (Dynamic Host Configuration Protocol) to assign temporarily an IP address to your terminal for the duration of the surfing session. In other words, your ISP leases an IP address to you for a period of time. When the lease expires, the client renews the old lease or gets a new IP address. You'll probably never receive the same IP address twice. This happens transparently and one neither needs to know or care what that temporary IP address actually is. You transparently access websites and email with the help of the DNS (Domain Name Server) system. Once a new computer is set to accept DHCP, it will function happily across the office network. When it comes to automation networks DNS names are seldom used for device identification. It would be impractical anyway because of the actions that must be taken in replacing a failed device .In the factory, the client (perhaps a PLC)needs to locate the server(s) - which are I/O devices - rather than the server locating the clients. More about this later. If a printer fails in your office and you replace it with another, the computers must be manually rebooted or configured to recognize the new printer. Not a big deal in the office environment but an unacceptable situation on the factory floor? Why? Because one can't re-configure a PLC program just because a photo eye fails. Constantly changing IP addresses are simply incompatible with the standard form of...

...Assignment 1 DNS and DHCP can make a system administrator's life simpler and easier. Fortunately, the protocols are so flexible that they can be implemented either together or separately depending on the size and configuration of your enterprise network. So whether you have 5 or 5000 computers in your network this would be justifiable action because of the following reasons: Looking up IP addresses can be a nightmare if you have more than a couple to remember If you have network-enabled printers, unless you lock the address, it will change every time you disconnect the printer from the network. This can be extremely frustrating for the users. If you have more than a small number of machines, then you should be looking at implementing DNS in addition to DCHP. There are a number of ways to implement DNS in-house depending on the specifics of the company computer systems architecture. The choice depends on the available skills in your shop and the network configuration. One nice thing about implementing DNS is that once it is set up, it pretty much runs without much need for human intervention. That means that if you hire a consultant to do the initial configuration, you only need to maintain the service with a minimum of skills and resources. I found two choices for configuring the service using Microsoft Active Directory or (the newest possibility) purchasing a DNS/DHCP service appliance. Whatever implementation you choose, once it is configured, the best DNS/DHCP server reliably...

Dns and Dhcp Overhead

...DNS and DHCP overhead DNS or Domain Name System is a service used by computers to translate human-friendly names into IP addresses. It’s like a phone book for the internet. DHCP or Dynamic Host Configuration Protocol is a networking protocol that configures devices that connect to a network can communicate on that network; it manages things like IP addresses, default routes and DNS server addresses. By using DNS and DHCP in concert, a site can happily grow to hundreds or thousands of nodes servers, desktop systems, laptops, printers, whatever, with minimal network/systems administrator effort. Both DNS and DHCP are essential tools in the network administrator's toolkit for managing all the IP devices on a corporate network. The more devices that require an IP address the more likely you are going to need DHCP and DNS to help maintain the IP addresses. The advantage of using dynamic IP addresses is that you avoid many common problems. For example, if you manually configure IP addresses, you must keep track of which addresses you have and haven't assigned, and to whom. If you accidentally assign two people the same address, of if a user monkeys around with his or her address, you can run into network problems that can be very hard to resolve. Furthermore, in many organizations, it's common practice to constantly move computers all over the building or between buildings. In such situations, if you were using static IP addresses, you'd be forced to change IP addresses to an...

Dns vs Dhcp

...DNS and DHCP, how they make your life easier DNS stands for domain name system, and DHCP stands for dynamic host configuration protocol. Most of the time they are used in conjunction with connecting to a network, though they are not reliant on each other, nor do you have to use either one to connect to your network. They just make the job of setting a network up that much easier, but you can still do everything manually if you choose to do so, it just won’t be anywhere near efficient. DHCP allows assigning IP addresses to computers on a network automatically instead of having to logon to each individual computer and set the addresses yourself, as well as keeping track of the addresses you have already assigned. DHCP takes place on your router, you connect your computer to the router, either wired or wireless, and the router automatically assigns an available IP address to the device and it keeps track of this so no two devices that connect to the router are given the same IP. If two devices with the same IP try communicate with the router, the device that connected first will work; the second device will act as if it has no connection. If the first device is shut down, the second device will then start to work, the network connection may need to be reset first though on the second piece of equipment. Two devices just can’t share the same IP address at the same exact time. A DNS server takes the domain name of a website and translates it into an IP address which a computer...
