DHCP Components Overview
DHCP is a server role that you can
install on Windows Server 2012. With the DHCP server role,
you can ensure that all clients have
appropriate IP addresses and network configuration information,
which can help eliminate human error
during configuration, DHCP is also a key
service for mobile users who change networks often
DHCP consists of the components that are listed in the
following table.
|
DHCP Server service
|
This service can distribute IP addresses and other network
configuration information to clients who request it
|
|
DHCP scopes
|
The DHCP administrator configures the range of IP addresses and
related
information that is allotted to the server for distribution to
requesting
clients
A scope must consist of:
• A name and description
• A range of addresses that can be distributed
• A subnet mask
A scope can also define:
• IP addresses that should be excluded from distribution
• The duration of the IP address lease
• DHCP options

DHCP options
|
You can configure a single DHCP server with multiple scopes, but the
server must be either connected directly to each subnet that it
serves, or
have a supporting and configured DHCP relay agent in place. The most
common DHCP options include:
• Default Gateway IP address
• DNS server IP address
• DNS domain suffix
• Windows Internet Name Service (WINS) server IP address
You can apply the options at different levels. They can be applied as
follows:
• Globally to all scopes
• Specifically to particular scopes
• To specific clients based on a class ID value
• To clients that have specific IP address reservations configured
|
|
DHCP database
|
DHCP database The DHCP database contains configuration data about the
DHCP server, and stores information about the IP addresses that have been
distributed. By default, the DHCP database files are stored in the %systemroot%\System32\Dhcp folder.
|
|
DHCP console
|
The DHCP console is the main administrative tool for managing all
aspects
of the DHCP server. This management console is installed
automatically on any server that has the DHCP role installed. However, you can also
install it on a remote server or Windows 8 client by using the Remote Server Administration Tools (RSAT) and by connecting to the DHCP server for remote management.
