You would need DHCP (Dynamic Host Configuration Protocol) when you want to automate the process of assigning IP addresses and other network configuration settings to devices on a network. This is especially useful in environments with many devices, such as offices or home networks, where manually configuring each device would be time-consuming and prone to errors. DHCP helps ensure that devices can connect to the network easily and reduces the risk of IP address conflicts.
By implementing DHCP, you would eliminate the need to set-up IP addresses manually. DHCP (Dynamic Host Configuration Protocol) simplifies the management of IP address configuration by automating address configuration for network clients.
ipconfig /release
At the DHCP server, you would create an address reservation. To do so, you need to know the host's MAC address for its network interface.
You dont *need* DHCP in AD. Although most people just use it anyway. However you do need DNS in an AD.
Those are the four phases of acquiring an IP address via DHCP. More information would be needed to indicate which of the 4 phases are being used at this point.
Router is usually configured as a DHCP client for WAN (Internet) network and as a DHCP server for local network.

How to setup shava tv plus ip dhcp
Benefits:1. DHCP is easier to configure, the network information does not need to be put into the computers on the network.2. Less network administration. If any information is changed in the future, like the gateway or DNS servers, they will be updated automatically.Drawbacks:Your IP address would change after being off for awhile, if you were trying to access that computer via hostname a ipconfig /flushdns would need to be performed first.Usually the Servers are static IP's and the workstations are DHCP.
DHCP support is already included in every distro capable of networking. It isn't a program; it's a basic part of the TCP/IP protocol.Answer:Well, if you are referring to the DHCP client, the program /sbin/dhclient is likely already installed on your Linux distro of choice.If you would like to run a DHCP server for one or more DHCP client machines or devices, you would go to www.isc.org and download the dhcp.x.x.x package (whatever the latest and greatest version is) and compile it on your Linux host machine. After compilation, configure it as desired, launch dhcpd (usually via the service command or directly from /etc/init.d), the DHCP daemon and you're ready to boot your DHCP clients.
It can if the administrator of the DHCP server has input incorrect values. DHCP is to provide a device with answers to commonly asked questions that it will need to correctly function in a network. If you can't get a DHCP address and everybody else can the problem is on your end most likely.
The benefit would be to automatically assign network addresses to clients that need them to work on a local area network. Without DHCP you would have to assign each device an address, subnet mask, and default gateway, plus DNS and WINS server addresses, which can be time consuming and error prone. With DHCP, most of those problems disappear.
