logresolve - resolve hostnames for IP addresses in Apache logfiles
logresolve [-c] [-s filename] < access_log > access_log.new
logresolve is a post-processing program to resolve IP addresses in httpd(8)'s access logfiles. To minimize impact on the 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. The following options are supported: -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 them matches the original address. -s filename Specifies the filename to record statistics.
