Nodetool status / nodetool ring will show an estimated ownership. They estimate
this by looking at the replication settings of one of the non-system keyspaces
(presumably those that contain actual data).
If they all have the same replication settings (say, RF=3 in each DC using
NetworkTopologyStrategy), then the ring/status ownership estimation can be
reasonably certain it’s correct – whatever value it will calculate is true for
If they differ, then it can print some ownership % from whatever keyspace it
selects, but that % will be different than if you chose a different keyspace.
In this case, pass the keyspace as the optional last argument to specify which
keyspace matters to you.

Subject: what does this Note mean?
Note: Non-system keyspaces don't have the same replication settings, effective
ownership information is meaningless
