Hostname Not Found

This may be a silly question, but what does "Hostname Not Found" really mean when displayed in the appendix of a vulnerability scan report?  We have an issue where a scheduled vulnerability scan that has worked and authenticated as expected for months, failed this weekend and again last night when reran.  The vulnerability scan report shows "Hostname Not Found" for 23 of the 24 servers.  The 24th server shows as being successfully authenticated with "Instance os:" and the IP address.  All of those servers should be using the same authentication record/method, so I'm scratching my head on this one.  I'm trying to track down any network changes that may account for this as well, but so far nothing.


Thank you for your input!
