Set DHCP to secondary IP address

Question

_{Wednesday, April 1, 2015 3:58 PM}

Hello.  I have been trying to figure out a way to set the DHCP server bindings to a secondary IP address on the same physical adapter as the primary address.  The OS is Windows Server 2012R2.  The server IP information is set as follows:

Windows IP Configuration
Ethernet adapter Ethernet:

   IPv4 Address. . . . . . . . . . . : 192.168.93.44
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   IPv4 Address. . . . . . . . . . . : 192.168.93.58
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.93.1

I would like for the DHCP server to answer on the .58 address, not the .44 address.  Is this possible?

Thank you.

Hi,

According to your description, my understanding is that DHCP server has 1 NIC (configured with 2 IP addresses), and you want the DHCP server to listen on 1 specific IP address.

By design, DHCP server bindings are enabled and disabled on a per-connection, not per-address basis. All bindings are based on the first configured IP address for each connection appearing in the Network Connections folder. If additional static IP addresses (for example, as set in Advanced TCP/IP properties) are configured for the applicable connection, these addresses are never used by DHCP servers running Windows Server and are inconsequential for server bindings.

Open DHCP console, right click DHCP server and select Add/Remove Bandings. You will see the available interface and IP address listed. You may change the order of the 2 IP addresses on TCP/IP properties, then re-open the banding list of DHCP server, the first IP address will be bundled to DHCP server by default.
