NAME
       logresolve - resolve hostnames for IP-addresses in Apache logfiles

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

DESCRIPTION
       logresolve is a post-processing program to resolve IP-addresses in Apache's access logfiles.  To minimize impact on your nameserver, logre-
       solve 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.

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.
