## Alternatives
-The alternatives would be to require everyone to have a dedicated

+We originally considered and rejected the idea that we could just leave

+example a blank provisioning network CIDR would indicate to disable the
+entire network. A blank DHCP range would indicate you wanted to use
+external DHCP. However, both of these fields have non-empty defaults

+The goal of the baremetal IPI initiative from the beginning was to offer

+majority, or at the very least some large plurality, of users. Removing
+default values and requiring users to specify them makes the platform

+If the majority of users will not want a provisioning network, then we
+could opt to make that change instead.
