      IMHO, this document does make clear the subtle issues with netmasks when setting up aliases.  As you know, aliases on the same network as the primary interface need a netmask of  255.255.255.255.  The first alias on a different network needs the correct netmask.  Additional aliases need to have 255.255.255.255.  IMHO, I think this document should cover these subtle issues with netmasks in more detail.

       This PR was prompted by helping other system administrators on IRC.
