+More practically, it could be useful to use IPv6 instead of
+renumbering that interface, since access is likely to be over
+link-local addresses anyways. This will enable IPv6 on the iDRAC
+interface and set a link-local address:

+    racadm config -g cfgIPv6LanNetworking -o cfgIPv6Enable 1

+The current network configuration (including the IPv6 link-local
+address) can be found in:
+
+    racadm getniccfg

+official documentation is rather hard to parse.
