Configure a DHCP Superscope

A superscope is running Windows Server 2008, you can create and manage the DHCP Microsoft Management Console (MMC) snap-in using the Dynamic Host Configuration Protocol (DHCP) server management functions. Through the use of the Super scope, can be used as a single administrative entity for grouping multiple scopes. To use this feature, DHCP server, you can:

• Multiple logical IP networks using a single physical network segment (such as a single Ethernet LAN segment) to support DHCP clients. When used on each physical subnet or network when more than one logical IP network, such configurations are often called multinets.

• Support remote DHCP clients are located on the far side of DHCP and BOOTP relay agents (network on the other side of the relay agent uses multinets).

In multinet configurations, you can use scopes global DHCP to group and to start on the network uses individual scope of IP addresses ranges of. In this way, the DHCP server can initiate and provide leases more scope to clients on a single physical network.

Superscopes can resolve multinets, including cases, certain types of DHCP deployment issues:

Pool of addresses available for the currently active scope is nearly depleted and need to add multiple computers to the network. Original scope includes the full addressable range for a single IP network address specified class. You will need to use a different range of IP addresses to extend the address space on the same physical network segment.

Clients must be migrated to a new scope (for example to renumber on an existing active scope to a new scope that contains another range of IP addresses for the beaches of current IP addresses that are used in the network).

You want to use two DHCP servers on the same physical network segment to manage separate logical IP networks.

Non-routed DHCP server (Before Superscope):

Small local area network (LAN) with one DHCP server supports a single physical subnet, subnet a. In this configuration is limited to the same physical subnet DHCP Server client leased addresses.

The following illustration shows how this sample network to its original state. Now that you have added no superscopes and scope of individual, range 1, used a. service all DHCP clients on the subnet.
