My desire was to make sure that Netview did not use the alias for the node
name. At another company I worked for we had dual-homed Digital Unix boxes.
Netview would 'arbitrarily' choose between one of the interfaces as a node
name. However, my question was to make sure that Netview did not use
aliases from the /etc/hosts file in the OVw database, which you have
confirmed.

Aliases provide additional names by which a forward lookup will
resolve to a given numeric address. They do not affect reverse
lookups.
The first name listed in /etc/hosts is the canonical name of the
device. When doing reverse lookups based on ip address (which is what
Netview is doing, a gethostbyaddr() i'm guessing), that canonical name
is what the system function returns.
If you want another name displayed, that one should be the first on
your list of aliases. You may need to delete the node and rediscover
it for that to happen, however.
