Sandra, I don't know that you can do anything about the default dns entries with the "-" appended, but you can give that interface an additional host alias for clean dns resolution:
nicaliases.eth1=node1.public.com https://xcat-docs.readthedocs.io/en/stable/QA/makehosts.html I do this quite a lot to get around that default naming behavior for other interfaces. Not sure if this is quite what you're looking for...
