It would be nice to automatically generate DNS names for non-primary interfaces. We for example assign <hostname>-ipmi.<domain> to our IPMI interfaces.

Perhaps a DNS name template.

v<%=interface.vlanid%>.<%=interface.name%>.<%=host.name%>.<%=host.domainname%>

If the template is configurable the end user can override the template.

What if the template can create an array.

[
 <%=interface.name%>.<%=host.name%>.<%=host.domainname%>,
 v<%=interface.vlanid%>.<%=interface.name%>.<%=host.name%>.<%=host.domainname%>,
]

Would result in two names being created with the IP of the interface.
