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 num‐
       ber 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.
