There is nothing inherently wrong with having two IPs for a given host name (often done in DNS for "DNS round robin load balancing"), although it's not often done mixing IPV4 and IPV6. As to why stuff on /mount would fail, that should have nothing to do with networking, unless the mounts are NFS or Samba mounts. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
