From AFP548 - Combining DHCP and DNS

Those geeks over at AFP548 have been at it again. I've always liked the integration between the DHCP and the DNS server in Microsoft's Active Directory. It's great to not have to use anything like $GENERATE statements to make a range of IP addresses for DHCP clients, and instead as a DHCP client gets an address, the DNS tables are updated with it's hostname.

Here's their writeup on how to combine DHCP and DNS on OS X Server. Unfortunately, you then won't be able to use Server Admin to control the whole lot, so you might want to get the DNS zone files set up with Server Admin first, and make sure that static addressing is all working, and then roll the config over to use with dynamic DNS updates.
