NAME
       logresolve - Resolve IP-addresses to hostnames in Apache log files


SYNOPSIS
       logresolve [ -s filename ] [ -c ] < access_log > access_log.new



SUMMARY
       logresolve  is  a post-processing program to resolve IP-addresses in Apache's access logfiles. To minimize impact on your
       nameserver, logresolve has its very own internal hash-table cache. This means that each IP number will only be looked  up
       the first time it is found in the log file.


       Takes  an  Apache log file on standard input. The IP addresses must be the first thing on each line and must be separated
       from the remainder of the line by a space.



OPTIONS
       -s filename
              Specifies a filename to record statistics.

       -c     This causes logresolve to apply some DNS checks: after finding the hostname from the IP address, it looks  up  the
              IP addresses for the hostname and checks that one of these matches the original address.
