dns

dns on
dns off
dns fast
If set to on, the dns option indicates that wusage should attempt to look up the host names of sites for which the access log contains only IP addresses. Note: the DNS option is not functional in the MSDOS version of wusage. It is functional in the OS/2 and Win 95 / Win NT versions as well as all Unix versions.

This is important: if your log already contains full host names for most sites, the dns option is not recommended. It is not likely that wusage will succeed in looking up the names of sites that your web server could not determine for itself, and a great deal of time will be wasted in the attempt.

If your log does not contain host names, then you may wish to turn on the dns option. Be aware that DNS (Domain Name Service) resolution is a slow operation which requires your computer to contact many other machines on the Internet. For faster results, set dns to fast. This will give you full host names in your reports. However, it does not provide enough information for the domains report or the ignoresites option to work properly. If you wish to use those features and your log does not already contain host names, you will need to set DNS to on. If you set the dns option to on, you will want to set up wusage to run automatically once a night, or once a week, using Unix cron or the Windows NT at command. Wusage is a fast program, but DNS is a slow operation, and it holds up the program considerably. See also the fakedns option, useful within company Intranets.
