Hi Ajaafar, a CSV export should do this, as long as you select the option for Export Data in Infoblox CSV Import Format. You can do this from Data Management->DHCP->Networks:
The CSV file you download will have the DHCP options for all the networks, including DNS servers. Keep in mind, if you want to only export a few subnets, you'll have to filter your view, otherwise you'll download a CSV file of all DHCP networks, which can get pretty large!
