Of course, I don't expect Pix to do reverse DNS resolution. I hoped that it would be able to extract this information from the HTTP request itself. The problem with reporting tools doing reverse DNS is that not all web servers have their IP configured for reverse DNS or they point to a generic name controlled by their ISP. This may generate confusing reports on what sites are accessed. The Configuration Guide for Pix gives a sample of URL logging syslog message where the name of the web site is recorded however, in reality that information is not there.
