DHCP custom options are used to define a nonstandard DHCP Client option that might be required by your software or applications.

A small number of custom options including option 150 (TFTP server), 176 (IP Telephones), and 252 (WPAD) are available in the Address Manager user interface as DHCP client options. Options that aren't included can be added as DHCP custom options.

You can create a DHCP custom option definition from a configuration’s DHCP Settings tab. After creating a custom option definition, it's available as a DHCP Client option. Add a DHCP custom option at any level where a native DHCP client deployment option can be assigned.
