Batch DNS Lookup Tool?

Looking up domain names from log files as batch process.

[eaken]

I'm looking for a tool that takes a raw log file as the input, and as the output provides the domain name of all the visitors.

In other words, it takes the IP field, does a DNS lookup, and returns the associated domain name.

Does anybody know what program I can use to find out what domain names are visiting my site. The IP itself is useless to us.

Thanks!

Try piping the logs through "logresolve" (command line):

logresove < inputfile > outputfile
