I'm curious how you normally deploy since there's a couple of ways to do it, I've mostly dealt with requesting a number of prefixes from the upstream router and delegating to each subnet/VLAN as appropriate, and each time I've done it it's been a breeze
Even if you need static addressing you can just set it manually and DAD will handle it if it ever conflicts with a DHCP address, at least in my experience
