About that "as secure as possible" bit.    If just one server gets
compromised that happens to have its IPMI port plugged into this
private network;  the attacker may  be able to pivot  into the IPMI
network  and start unloading IPMI exploits.

So caution is definitely advised,  about security boundaries: in case
a shared IPMI network is used,  and this  is a case where a Private
VLAN   (PVLAN-Isolated)   could be considered,   to ensure devices on
the IPMI  LAN cannot communicate with one another ---  and only
devices on a separate dedicated IPMI Management station subnet  can
interact with the IPMI LAN.
