The Page/File by Machine Name Report tabulates the number of page and file requests in the given time frame grouped by the machine name where they originated.  In this report, the program will list the client machines as they appear in the web server log, either by IP address, or by Domain Host Name.  In this report, host name prefixes, if they exist are counted as separate machines.  For example, if the web server log file included the computers outbound6.hisoftware.com and outbound7.hisoftware.com, those would be counted as two separate computers.
