<span style="color: #000000">You can use option filters to classify DHCP clients and decide which DHCP options each group of clients can receive. By default, regardless of the subnet in which the DHCP clients reside, all DHCP clients that match the filter criteria receive the DHCP options and values you define in the filter. You can change this configuration so the application does not use the filter to classify DHCP clients. For information about how to configure this, see </span><span style="color: #000000">*[Creating Option Filters](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneDDI/pages/186648616)*</span><span style="color: #000000">.</span>

<span style="color: #000000">You can add DHCP options and the Hardware Operator option to an option filter. For information about the Hardware Operator option, see </span><span style="color: #000000">[Creating IPv4 Hardware Filters](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneDDI/pages/186466697)</span><span style="color: #000000">.</span>

<span style="color: #000000">After you define an option space and add options to it, you can set up option filters and define option values. For example, to handle two different client classes, you can define two option filters (vendor-class_1 and vendor-class_2) and send different option values to different clients based on the vendor-class-identifier options that you obtain from the clients.</span>
