<p>Isn't this a major loss of functionality? Is there a plan /
ticket to add this core feature?<br>
</p>
<p>Manually maintaining IP reservations in multiple places (DNS,
Reverse DNS and DHCP) is a pita that is prone to error. </p>
<p>Decisions on IP range allocation fit more naturally in DNS as
pre-release testing there can confirm that both forward and
reverse IP allocation is consistent. </p>
<p>Surely you don't expect DevOps to maintain forward IP allocation
in DHCP and reverse allocation in DNS?</p>
