You really don't need to do that. Just use an IP mapping scheme,
restrict the DHCP range, and manually assign static server addresses
from a known range.

Well, yes, you can reserve addresses by MAC address, use DDNS with your
DHCP server to update DNS, but why? Servers should always be effectively
static; any scheme that assigns addresses to them increases complexity
and the possibility of problems.
$0.02.
