Creating IPv4 DHCP Scopes
Before a DHCP server can be useful, it must
be authorized, and a scope must be created and activated. DHCP
authorization can be performed using the DHCP Post-Install Wizard or it
can be performed from within the DHCP server console. This section
details how to create a basic DHCP IPv4 scope on a newly authorized
DHCP server. To create a new DHCP IPv4 scope, follow these steps:
1. On a server with the DHCP Server Tools installed, click the Server Manager tile on the taskbar.
2. When the Server Manager console opens, click Tools, and then select the DHCP option.
3. If no servers are listed when the DHCP console opens, right-click DHCP in the tree pane and select Add Server.
4. In the Add Server
windows, if the server is already authorized, select it from the
Authorized Server section of the window and click OK, as shown in Figure 3. If the server is not yet authorized, type in the server name, and then click OK to continue.

5. After the server is
added to the console, expand the server to reveal the IPv4 and the IPv6
nodes. Verify that both nodes show a green checkmark indicating that
the server is properly authorized in Active Directory.
6. Select the IPv4 node, and then right-click and select New Scope.
7. Click Next on the Welcome to the New Scope Wizard.
8. On the Scope Name page, provide a description name and description for the new scope, and then click Next to continue.
9.
On the IP Address Range page, enter a starting and ending IP address
and a corresponding subnet mask for the new scope, and then click Next
to continue, as shown in Figure 4.

10. On the Add
Exclusions and Delay page, enter any IP address exclusion ranges or
DHCP subnet delay intervals, and then click Next to continue.
Note
DHCP administrators wanting to deploy
redundant servers or split-scope ranges should leave the fields on the
Exclusion and Delay page blank and run the Failover or Split-Scope
Wizards to achieve the desired redundancy configuration.
11. On the Lease
Duration page, adjust the lease duration from the default of 8 days to
the desired IP address lease duration and click Next to continue.
Typical durations include 1 day, 8 hours, or 30 days, depending on the
organization.
12. On the Configure
DHCP Options page, select the Yes I Want to configure Options Now radio
button and click Next to continue. The wizard then steps through the
configuration for the most common DHCP scope options that
administrators desire, such as the Router (Default Gateway) option, the
Domain Name Suffix & DNS Servers, and WINS Servers.
13. On each of the options pages, enter the appropriate information and click Next to continue, as shown in Figure 5, when configuring the domain name suffix and the DNS servers.

14. On the Activate Scope page, select the Yes, I Want to Activate This Scope Now radio button, and then click Next.
15. Click Finish on the Completing the New Scope Wizard page.
16. After the scope
has been created, expand the IPv4 node to reveal the new scope and
review each of the subnodes to ensure the correct settings were
deployed.
This completes the deployment of a new IPv4 DHCP scope.
