Which seems to be exactly the behaviour documented in net_adm(3):
This function calls names(Host) for all hosts which are speci-
fied in the Erlang host file .hosts.erlang, [...]
Since your .hosts.erlang on host C has only A and B, you shouldn't see
the nodes on C when you run net_adm:world/0 there.

Seems like a good idea to do that then:-) (and ditto on A and b), since
it's clearly the intent.

Yes, if they really include themselves in the list, it's strange - are
you sure you aren't actually seeing 4 nodes from net_adm:world/0 on them
rather than 5? I.e. two@REDACTED, three@REDACTED, four@REDACTED, and five@REDACTED on A, and
correspondingly on B.
