Wide-Area Bonjour Configuration in Private IP Network

I understand the need for a DNS Server with a zone created for .local according to dns-sd.org. But in order to achieve Wide-Area Bonjour in a Private network multi vlan enviroment does the dns also need to take advantage of isc-dhcp for dynamic updates or will Apple default dhcp be enough ? I am trying to receive a list of all devices in my cloud made up of multiple vlans through broadcast.
